Nope, I didn't. It simply isn't necessary in the simple one and two tube amps I'm showing how to ground. It is rarely practical to use a single one for everything from the power supply to a phono catridge input stage. Okay, if you say so, I believe that you don't have the brains or the attention span to work out a proper grounding scheme. But where is the phone cartridge in the integrated linestage one- and two-tube SE amps I showed? I see absolutely no practical problem -- in fact there is none because I built those amps already, many times. with single star grounds. As usual, Poopie, you're talking in generalities through the back of your neck. Also, you clealry don't understand why it's important. You produced a 'recipe' without being able to explain it.

So, when I invite you to prove a single error in my scheme, surely this is your chance to prove "accepted practice" wrong. Instead you give us another childish generality. As Henry very correctly says, it's important to UNDERSTAND why one uses these techniques. Yes, yes, yes, I often say the same thing when I'm too lazy to provide useful information. it is just another generality. You, Poopie Stevenson, and that moron Henry Pasternack, tried to say there is something wrong with the scheme I put up. You've had several chances now to specify a single error, and you have failed. All we hear from you two jerkoffs is idle generalities, pompous tenth- rate wittering. Graham Unsigned out of contempt |

Iain Churches wrote: "Patrick Turner" wrote in message ... Iain Churches wrote: Patrick posted some interesting facts about ground buss connections, which I have extracted from another thread and pasted here, because I think the subject is important enough to warrant its own thread. He wrote: The 0V rail of the preamp should be a short buss wire about 100mm long with ends connected to the RCA plug 0V bodies at inputs and outputs. ALL parts with OV connections should be made to this buss, and the CHASSIS or CASE connected via a 5 watt 27 ohm R, and the case taken to the green/yellow wire to the wall socket so the case can't become live to mains or the B+. There should be NO direct connection of the OV buss to the case. -- I ask: In other words the mains supply case should be bonded to the case, and the 0V (signal grounds) taken to the ground point via a 27 Ohm 5W resistor? Why is this? Because chassis can have magnetically induced voltages in them, they should never be used for the 0V rail. And why 25W? I said 5W, but 25W would be OK. Because you don't want that R to go open, ever, or the whole audio circuit IS NOT REFERENCED TO THE CHASSIS AND EARTH, something I feel is important. If the B+ becomes shorted to the chassis, you want the fuse to blow because of that short. You DON'T want a 27 ohm x 1/4 watt R to fuse open in an instant, leaving the 0V rail at +500V, including the OV rail and the speaker wires.... Hope for the best with your amps, but ALWAYS prepare for the worst! Patrick Turner. Iain |

Andre Jute wrote: snip for brevity, Most schematics don't tell you enough about earthing. This is a very true statement if ever there was one. A schematic is just how things are connected, and sure, worth a thousand words. But they are often utterly useless in telling folks how to layout the circuit and placement of parts and wiring for best operation, freedom from micro power supply rectifying noise voltages in 0V wiring, magnetically induced mirco voltages, and return current effects in load current carying wiring etc etc etc. A lot is left for the maker to get right. Countless times diyers construct something with the exact and right schematic but are left with deafening hum and noise problems, and with maybe RF oscilations as well, all because of very poor understanding of most basic aspects of electronics. When told to spend weeks doing some real learning, they just cannot do it because they don't have a questioning mind. In a recent case a guy with an old tubes CJ preamp had me instal a fet cascode circuit for the MC input to suit his MC cart because the CJ had a rather poor tubed phono rendition fit only for high output MM. I finally got the 0V pathing adjusted after several hours to give negligible hum when the preamp gain was set to normal operation level with an average power amp connected with a speaker. He appreciated the revaltion the MC cart gave him. Then he wanted all the crummy old 1960s RCA sockets replaced to stop the intermittent noises he was getting. My time is valuable, and too valuable to do the donkey work of replaceing RCA sockets, so I insisted he learn to use a drill and make a new panel and pay for some Cardas sockets and do it himself. Of course he insisted on remaining a practical klutz, and talked his dad into doing this highly skilled but tedious task for nothing of course. His dad wanted to keep the exact positions of the existing RCAs the same so as not to disturb what 0V rails I had arranged initially. But the guy had his dad change the positions to suit two different sizes of new RCAs, so that phono input wiring was 150mm longer, and woe, he used untwisted 1mm thick house wire type wires. When he tried te amp, its hum was quite deafening, and ther amp was unusable, so he comes across town to me for a fix, cheaper than learning anything. I re-route the cabling internally to where it was, but get him to agree there was no difference in quality the two sizes of RCA sockets, so no need to make the compromise in positioning just because of some wacky idea about the RCA socket quality. He went away after $50 worth of work which stuffed my afternoon on a saturday but he had a Turnerized Conrad Johnson that wasn't noisy any more, and he had some real understanding of how bleeding important it is to consider everything about all aspects of what you're doing when making any changes to circuits. Here, for instance: http://members.lycos.co.uk/fiultra/Jute-EL34-SEntry.jpg I've shown the star earth being implemented but have not said anything about connecting the case to earth. Mind you, on some of the Lundahl Modular Series 300B schemos I showed all the 0V connections in order, with a note saying "mind the order of the grounding connections", and two people wrote me letters saying that DIYers are not idiots who need their hands held. (I was, when I started, and I'm very grateful to people who made 90 mile round trips to come check over my constructions before I fired them up.) The schema above is fine, but has no chassis shown, so I suggest 27ohms x 5W from star 0V point to chassis point near the RCA inputs and well away from the PT. The mains green / yellow earth wire sould also be taken to a chassis point away from the PT, and not necessarily to where the 27ohm is anchored, to reduce induced chassis voltages..... I might add that 0V rails layout is even MORE critical in high powered SS amps... Patrick Turner. |

Henry Pasternack wrote: Andre Jute wrote: A star ground is just a circular bus or a very short bus. Not really, ANDRE. A star ground is the abstract notion of a purely equipotential (equal voltage) single point connection that eliminates ground loops by reducing the resistance of the common ground bus to zero. It's impossible to achieve in practice, though, and trying to take the approach too literally is likely to cause more harm than good. Don't you mean more hum than silence? Grounding is is tricky and tiresome in inverse proportion to the amount of thought you give it. I would say the opposite is true. The less you think about grounding, the less tricky it seems. It depends on what knowledge is in the thinker's mind and how good at thinking they are. With no thought at all, it becomes as simple as pie. Or fruit tart, for that matter. Just connect all the ground connections together any way you like, and don't worry. It's only when you start to think about it that it truly becomes tricky. Oh my Gord, while your at it, just connect all components up to randomly chosen circuit points and tube socket pins. Avoid all thought, and never check what you are doing. Turn it on with bravado, and cheer as the smoke rises and parts fry to death. But maybe it doesn't hum, so mission accomplished. That other re-posted advice does ahve lots of good stuff people should realise and practice automatically while thinking about how to make their amp. So we won't take you seriously always and we will keep smiling... Here you can see my star point [URL deleted]. You may be able to see it, but to my eyes the picture is impossibly tiny to reveal any useful details. But, you know I have this problem with photographs. Most schematics don't tell you enough about earthing. Here, for instance: [URL deleted]. I've shown the star earth being implemented but have not said anything about connecting the case to earth. Attempting to connect all the grounds together like that, willy-nilly, is not the right approach. That's because in practice it's nearly impossible to achieve a true equipotential connection for all those wires. Also, there are other performance issues having to do with all those long ground connections running about the amplifier. ... I showed all the 0V connections in order, with a note saying "mind the order of the grounding connections", and two people wrote me letters saying that DIYers are not idiots who need their hands held. Then the DIYers were idiots, because the subject is quite worthy of elaboration. The problem I see with everything you say here is that you fail to address the most important meat of the problem, which is precisely how to determine the "order of the grounding connections" and how this translates into a practical wiring and ground layout. That does take practised skills which are best learnt by trial and error by diyers in their own shed. All the discussions in the world about grounding on new groups won't stop diyers getting things wrong a few times unless they learn, and some cannot, or simply will not, because its cheaper to go to a tech person to sort their mistakes. Even when I point out they ARE ABLE to work it out and learn, and that they DO HAVE the time, they won't learn, and won't use the time, and prefer to do such dumb**** things as attend pubs and watch TV and have reams of useless small talk with others around them. So urging Andre, or myself, or to give a diagram of how-to-do yourself will have almost zero effect on the hum found in diyer first attempts. I had to teach myself. And I built test gear for measuring low mV level signal volts and currents so I needed to know how to make circuits quiet. At first they were hopelessly too noisy, but gradually I got really good at eliminating noise. It took days and weeks of practice. My opinion on this subject is there are many ways to wire an amplifier to minimize hum and noise. Star grounding (and its variants) and bus wiring are two common solutions. Well, starring is the most predictable. It usually gives a fair result. But you end up using more hook up wire than you'd like to so avoiding lengthy wires from PS cap 0V terminals to a point near the input is investigated. Finally, the idea of referencing is formed in the diyer's mind, and ideas about never allowing a PS supply wire carrying heavy ac or dc to appear commom to other 0V wires which may produce some noise at the input. Pictures and vague generalities, if you would like to help your readers, you should teach them the principles involved (you do know them, right?) so they can work out the optimum grounding scheme for each project by themselves. Well, for any given amp, very few variations of the 0V path will give noise free operation. determined diyers will find them through their own efforts at educating themselves on the basics about circuit currents flowing around the bloody circuits they are building. But its a big expectation to expect people to prove anything to themselves; many people prefer chocolate to apples, and bull**** to truth.... Of course, being a lying psychopath pornographic scumbag, I may not really know what I'm talking about! Feel free to ignore everything I say. In fact, I strongly urge you to do so! :-) I have never found you to be a clueless scumbag full of porno and don't have the time to determine if its true or not. Porno is art to many folks, unless its porking 1 year olds, and thankfully we don't have images allowed at r.a.t, where no doubt a small minority would make use of the binaries ability to post inappropriate images which may be distracting to tube craft. I find it difficult to think about sex and +700 V at the same time. If you sent me an image of yourself or even myself porking Queen Elizabeth II, I'd be mildly amused, and know there was no accounting for taste, eh. I have Nicole K and Kylie M here this minute to mow my lawns because they get so tired of the work they do. I also want them to clip the hedges, and they are having a little argy bargy about who gets up the ladder, and who holds the ladder steady... I'll bring them a nice cup of tea when they finish and we'll have a nice swim in the pool after. About 50 laps should tire them out naturally. r.a.t is democracy without regulation, and its a lot better than elsewhere.... Patrick Turner. -Henry |

When somebody talks about "professional" people involved in audio, or candle making, or even **** carting, I am always a cycnic until their activities proove otherwise. They must first proove they know their trade and craft. The doctors who regard themselves as professionals took a whole year to correctly diagnose the ovarian cancer my sister got. They thought she had indigestion, a stomach bug..... By the time she got diagnosed properly, she had incurable cancer that had spread to her lungs and stomach and bowel and she died 15 months later after huge amounts of treatments which didn't work. They first told her she had an 80% chance of being alive in 5 years. But my search in Google said she had 67% chance of dying within 5 years even if they'd diganosed correctly 12 months earlier than when thy did find outabout. So when she was diagnosed, she had NO chance whatsoever of surviving. But we got bull**** about 80%. "Professionals" tell lies and bull****. They charge outrageous prices for this crap. Sure some are what we need, but some have no clue. Patrick Turner.

Avoiding ground loop issues you need to understand the paths the
currents thru such a ground are taking. And remember that all real conductors have resistance, and that "noise" voltages will develop across those current paths. Using dedicated wires for each current path avoids this. That's what you do in a star ground system. One important current path is the one in the power supply. From the center-tap of the high voltage secondary to the filter cap is a high current spike every 120th of a second. SO to keep that out of the rest of the amp, you connect the secondary center-tap directly to the negative side of the filter caps, and then what becomes the B- (at the filter cap negative) then becomes a wire leading to the star ground. I've connected my output stage cathode resistors to this B- point, and then use the star ground for low current low signal level work. |

Andre Jute wrote: *snip for brevity, Most schematics don't tell you enough about earthing. This is a very true statement if ever there was one. A schematic is just how things are connected, and sure, worth a thousand words. But they are often utterly useless in telling folks how to layout the circuit and placement of parts and wiring for best operation, freedom from micro power supply rectifying noise voltages in 0V wiring, magnetically induced mirco voltages, and return current effects in load current carying wiring etc etc etc. A lot is left for the maker to get right. Frankly, Patrick, my opinion after nearly twenty years in DIY tube audio is that, were you and I to collaborate on a book on grounding, ti would uneconomically thick, it would still be incomplete, and the little hotheads and know-alls, as in your example below, would still screw it up. And the self-declared "professionals" like Poopie and Plodnick would still screech down from their ivory towers without adding anything of any practical use to the discussion. BTW, I use and appreciate Carda connectors. They're nice to handle and the gold plating is done over the proper underlayers, unlike so much American plating which is shoddy. I have left the rest of Patrick's post because it bears on what I say, and is funny besides. Andre Jute Visit Jute on Amps at http://members.lycos.co.uk/fiultra/ "wonderfully well written and reasoned information for the tube audio constructor" John Broskie TubeCAD & GlassWare "an unbelievably comprehensive web site containing vital gems of wisdom" Stuart Perry Hi-Fi News & Record Review Countless times diyers construct something with the exact and right schematic but are left with deafening hum and noise problems, and with maybe RF oscilations as well, all because of very poor understanding of most basic aspects of electronics. When told to spend weeks doing some real learning, they just cannot do it because they don't have a questioning mind. In a recent case a guy with an old tubes CJ preamp had me instal a fet cascode circuit for the MC input to suit his MC cart because the CJ had a rather poor tubed phono rendition fit only for high output MM. I finally got the 0V pathing adjusted after several hours to give negligible hum when the preamp gain was set to normal operation level with an average power amp connected with a speaker. He appreciated the revaltion the MC cart gave him. Then he wanted all the crummy old 1960s RCA sockets replaced to stop the intermittent noises he was getting. My time is valuable, and too valuable to do the donkey work of replaceing RCA sockets, so I insisted he learn to use a drill and make a new panel and pay for some Cardas sockets and do it himself. Of course he insisted on remaining a practical klutz, and talked his dad into doing this highly skilled but tedious task for nothing of course. His dad wanted to keep the exact positions of the existing RCAs the same so as not to disturb what 0V rails I had arranged initially. But the guy had his dad change the positions to suit two different sizes of new RCAs, so that phono input wiring was 150mm longer, and woe, he used untwisted 1mm thick house wire type wires. When he tried te amp, its hum was quite deafening, and ther amp was unusable, so he comes across town to me for a fix, cheaper than learning anything. I re-route the cabling internally to where it was, but get him to agree there was no difference in quality the two sizes of RCA sockets, so no need to make the compromise in positioning just because of some wacky idea about the RCA socket quality. He went away after $50 worth of work which stuffed my afternoon on a saturday but he had a Turnerized Conrad Johnson that wasn't noisy any more, and he had some real understanding of how bleeding important it is to consider everything about all aspects of what you're doing when making any changes to circuits. Here, for instance: http://members.lycos.co.uk/fiultra/Jute-EL34-SEntry.jpg I've shown the star earth being implemented but have not said anything about connecting the case to earth. Mind you, on some of the Lundahl Modular Series 300B schemos I showed all the 0V connections in order, with a note saying "mind the order of the grounding connections", and two people wrote me letters saying that DIYers are not idiots who need their hands held. (I was, when I started, and I'm very grateful to people who made 90 mile round trips to come check over my constructions before I fired them up.) The schema above is fine, but has no chassis shown, so I suggest 27ohms x 5W from star 0V point to chassis point near the RCA inputs and well away from the PT. The mains green / yellow earth wire sould also be taken to a chassis point away from the PT, and not necessarily to where the 27ohm is anchored, to reduce induced chassis voltages..... I might add that 0V rails layout is even MORE critical in high powered SS amps... Patrick Turner. |

Not really, ANDRE. *A star ground is the abstract notion of a purely equipotential (equal voltage) single point connection that eliminates ground loops by reducing the resistance of the common ground bus to zero. *It's impossible to achieve in practice, though, and trying to take the approach too literally is likely to cause more harm than good. Don't you mean more hum than silence? Porno Pas has built two or three tube amps in his entire life, total, max, final count. What he says is hardly ever specific enough to be useful, and my experience is that he tailors the truth about electronics according to who he speaks to. In short, Henry Pasternack is unreliable, often dangerous. I have no problem believing that a Pasternack amp produces "more hum than silence". Why, even Jon Yaeger, hardly the most discriminating tubie, broke up one of Pasternack's amps, presumably because it was too noisy to use or sell on. Pasternack can't even keep his story straight in a single letter. He contradicts himself repeatedly in the letter you're replying to. Andre Jute "I was at a board meeting for the LA Chapter of the Audio Engineering Society last night on XM Satellite radio audio and data transmission. Sadly, we missed you there, and at the SMPTE and Acoustical Society recent meetings as well. Everyone was asking, 'Where is that wonderful Andre Jute? The world just doesn't rotate without him...'" -- John Mayberry, Emmaco Grounding is is tricky and tiresome in inverse proportion to the amount of thought you give it. I would say the opposite is true. *The less you think about grounding, the less tricky it seems. It depends on what knowledge is in the thinker's mind and how good at thinking they are. With no thought at all, it becomes as simple as pie. *Or fruit tart, for that matter. *Just connect all the ground connections together any way you like, and don't worry. *It's only when you start to think about it that it truly becomes tricky. Oh my Gord, while your at it, just connect all components up to randomly chosen circuit points and tube socket pins. Avoid all thought, and never check what you are doing. Turn it on with bravado, and cheer as the smoke rises and parts fry to death. But maybe it doesn't hum, so mission accomplished. That other re-posted advice does ahve lots of good stuff people should realise and practice automatically while thinking about how to make their amp. So we won't take you seriously always and we will keep smiling... Here you can see my star point [URL deleted]. You may be able to see it, but to my eyes the picture is impossibly tiny to reveal any useful details. *But, you know I have this problem with photographs. Most schematics don't tell you enough about earthing. Here, for instance: [URL deleted]. *I've shown the star earth being implemented but have not said anything about connecting the case to earth. Attempting to connect all the grounds together like that, willy-nilly, is not the right approach. *That's because in practice it's nearly impossible to achieve a true equipotential connection for all those wires. *Also, there are other performance issues having to do with all those long ground connections running about the amplifier. ... I showed all the 0V connections in order, with a note saying "mind the order of the grounding connections", and *two people wrote me letters saying that DIYers are not idiots who need their hands held. Then the DIYers were idiots, because the subject is quite worthy of elaboration. *The problem I see with everything you say here is that you fail to address the most important meat of the problem, which is precisely how to determine the "order of the grounding connections" and how this translates into a practical wiring and ground layout. That does take practised skills which are best learnt by trial and error by diyers in their own shed. All the discussions in the world about grounding on new groups won't stop diyers getting things wrong a few times unless they learn, and some cannot, or simply will not, because its cheaper to go to a tech person to sort their mistakes. Even when I point out they ARE ABLE to work it out and learn, and that they DO HAVE the time, they won't learn, and won't use the time, and prefer to do such dumb**** things as attend pubs and watch TV and have reams of useless small talk with others around them. So urging Andre, or myself, or to give a diagram of how-to-do yourself will have almost zero effect on the hum found in diyer first attempts. I had to teach myself. And I built test gear for measuring low mV level signal volts and currents so I needed to know how to make circuits quiet. At first they were hopelessly too noisy, but gradually I got really good at eliminating noise. It took days and weeks of practice. My opinion on this subject is there are many ways to wire an amplifier to minimize hum and noise. *Star grounding (and its variants) and bus wiring are two common solutions. Well, starring is the most predictable. It usually gives a fair result. But you end up using more hook up wire than you'd like to so avoiding lengthy wires from PS cap 0V terminals to a point near the input is investigated. Finally, the idea of referencing is formed in the diyer's mind, and ideas about never allowing a PS supply wire carrying heavy ac or dc to appear commom to other 0V wires which may produce some noise at the input. Pictures and vague generalities, if you would like to help your readers, you should teach them the principles involved (you do know them, right?) so they can work out the optimum grounding scheme for each project by themselves. Well, for any given amp, very few variations of the 0V path will give noise free operation. determined diyers will find them through their own efforts at educating themselves on the basics about circuit currents flowing around the bloody circuits they are building. But its a big expectation to expect people to prove anything to themselves; many people prefer chocolate to apples, and bull**** to truth.... Of course, being a lying psychopath pornographic scumbag, I may not really know what I'm talking about! *Feel free to ignore everything I say. *In fact, I strongly urge you to do so! *:-) I have never found you to be a clueless scumbag full of porno and don't have the time to determine if its true or not. Porno is art to many folks, unless its porking 1 year olds, and thankfully we don't have images allowed at r.a.t, where no doubt a small minority would make use of the binaries ability to post inappropriate images which may be distracting to tube craft. I find it difficult to think about sex and +700 V at the same time. If you sent me an image of yourself or even myself porking Queen Elizabeth II, I'd be mildly amused, and know there was no accounting for taste, eh. I have Nicole K and Kylie M here this minute to mow my lawns because they get so tired of the work they do. I also want them to clip the hedges, and they are having a little argy bargy about who gets up the ladder, and who holds the ladder steady... I'll bring them a nice cup of tea when they finish and we'll have a nice swim in the pool after.

Wouldn't it be -500V on the "OV rail and the speaker wires" if the B+ shorted to the chassis, or does it just look that way to me because I am standing on my head? Regards, John Byrns Indeed you are right, but if the 27R went open, and B+ shorted to the chassis, then the chassis would try to go +ve, and 0V rail and speakers etc would try to go very negative. BUT, if you had a preamp attatched, with coaxial RCA cable connecting the power amp 0V to preamp 0V, and there was a similar 27 ohms in the preamp to its chassis and Earth, then the preamp's "ground lifting resistance" of 27ohms might also fuse open, and you'd get a high -Ve voltage at the RCA 0V terminal and speakers so if you touched this or speakers and the chassis which IS at earth potential, you'd get a bad shock. So hence the need for the ground lift R to be rugged enough so when such a B+ to ground short occurs, a mains fuse will blow because of the low load on the power supply. Its very unlikely you'd ever get the B+ shorting to the chassis. Its much more likely that a B+ short to 0V would occur, through a stuffed output tube, or from P to S on the OPT, or from an arc across from pin 3 to pin 2 on octal sockets. So its likely that the 27R isn't ever exposed to a sudden amount of high current. But **** happens, so prepare for it. The point I was making is that all chassis should be well connected to EARTH, and then if ground lift between chassis and 0V rail is the standard way to lower noise, then for safety use a high wattage low value ground lift R which still has MUCH more resistance than the coax outer shield of an interconnect to some other component such as preamp or cd player, tuner etc. Patrick Turner. -- Surf my web pages at, http://fmamradios.com/ |

Andre Jute Our legislators managed to criminalize fox-hunting and smoking; when will they get off their collective fat backside and criminalize negative feedback? It is clearly consumed only by thickoes. |

And who the hell are these 'professionals' you refer to ? The standards in pro-audio are normally first class. Huh? Are you an example of what you consider a "professional in pro- audio", Poopie? If you are, the standards must be deplorably low. A typically ignorant statement from you. How can *any* statement from me be ignorant after all the great newspapers of the world have lauded me for my research, never mind "typically ignorant". Get a grip, Poopie. Since when have you ever examined any equipment designed by me ? Why, have you sent me some? It never arrived. Graham Calm down, Poopie. Get your blood pressure under control. This can't be good for you. Andre Jute Calm, reasonable, cool |
