I would refer you to Matthew 7:3, King James, were you to have any hope of understanding its meaning. If you want to argue on those grounds Peter, they apply to you no less than I. (no pun intended). If you had any "insight" at all, you would understand that you have no place here, But I do - I help keep you hyperactive children grounded. that you are pretty much universally reviled here, Speaks more about the revilers than I. and that you will have no net effect here of any nature other than to give some of us a chance to polish our invective. If you are polishing your invective Peter, then try a different approach. You are becoming less polished, not more polished. Sadly, as you do have such trouble with the rules and forms of logic, Easy to say, but impossible to prove. Just crass invective. the meaning of words and the English Language Again, just a cheap shot from a cheap mind flapping cheap lips. in general, most of that is lost on you. Letsee, are childish insults lost on me? Yes, guilty as charged! Repeat: you are a poor, sad, delusional sod. That's just crass repetition. Peter, do you know what they say about people who repeat the identical same actions with the hope of getting a different result? That's you! I think I might add 'ignorant' or 'obtuse' next time. Been there, done that. But I think that 'delusional' covers it pretty well for now. Good self-diagnosis, Peter. You should reread some of your older stuff, when you were more in touch with yourself. What I see is a little man with a frustrating life's situation who needs to dump his bile on someone, once or more a day. If Jute is out of town and West is working off his Honey-Do, then there's always moi! |

As if the preceeding series was not a stream of such offenses, Peter. I've got you figured out Peter, you are without fault in your own eyes. We enjoy ourselves and our hobbys. Apparently, not without a need to try to capture a few scalps. Then along come whining magpies such as you driven to engage in a futile attempt to spoil the enjoyment by pointing out ad nauseum the faults of tubes - all of which are well understood anyway. Really. If those faults are so well understood and accepted, then why all the wailing and gnashing of teeth when they are pointed out? Again, you have no place here. As you describe RAT, neither do you, Peter. Better for you and your delusions to go somewhere you might be respected or your opinions valued. That is certainly not here. So says the one with no personal insight, the one who has to be faultless in his own eyes. As to Jute and Pillock - Jute is capable of on-topic posts, has actually worked with tubes even if the product is of dubious function and output (no fault of the tubes in his case) If having worked with tubes, or owning tubed equipment grants one absolution, why not for myself? and other than being a supreme egoist does seem to take some enjoyment out of life even if he lives it in near-darkness. West is a young, damaged fool in search of a legend for himself hero to worship but not necessarily irredeemable. Fact is Peter you see me as a threat. You are none of the above. Good example of how delusional and filled with hatred that you are, Peter. It appears from your posts here that you have no function in your life or hobbies other than to be annoying. Back at you, Peter. , my what an utterly stunning ambition. It's all a figment of your fevered little mind, Peter. |

Well, I'm referring to a time some number of months back. How many I'm not sure. Mybe 4-5 or more. I don't know if it worth it to research google to put an exact date on it. But, don't tell me what date it is, in case I do the research later on. Knowing when he was in the kingdom would bias me. |

I like building the old circuits. Some of them sound surprisingly good. You bet! Just because a design and a tube are old does not mean they are not a good. I have designed and built a stereo SET amp using a 6SL7 in each channel (SRPP circuit) driving a paralleled pair of 2A3's in each channel. Although I have several more modern designs delivering a lot more power, I still tend to prefer this SET triode amp. As was said, some old tubes and circuits do sound surprisingly good. |

building a PP amp
Ray's a good guy, and if he's listening then I have a few points. I
build with the 71A amongst other DHTs and I also use the 124b. In one incarnation I did find the 124b lost some bass, but in another the bass was certainly there. So I'd guess it's a question of DC balance - I doubt whether they tolerate any. I've been building fairly quickly because I don't have too much free time, so I can't give you actual voltages, but at some point I'll look closer at the 124b to see what's going on. I do, however, like its midrange and treble. But why not go further and add an output stage - 71A is one of the great drivers. Andy |

The price was certainly right on the 124B and I thought with the 49% nickel core, it would do OK, but the bass is really lacking in this build. It drops off pretty steeply at 80Hz. This circuit is so simple that I really don't see what else I might do to improve the bass except to use a better transformer. I'm looking at the Lundahl LL1660S which costs about five times what I paid for the Hammonds. I'd be interested to see your circuit and any suggestions you might offer as a way to balance the DC (although I don't see how I could get any on the grids since the CT of the IT is grounded) and improve the bass response. I suspected from the start that I might have a bass issue due to the published specs, but with the price point, I thought I'd give it a try. I'm driving the 124b with a 56 at about 4.5mA and a bypassed RK. It looks OK on the scope, so that's what leads me to think it's the IT. As to an output stage, I'm building this as an amp for my office, so I really don't need more than a couple of watts. I have used DHTs for drivers, 300Bs driving 845s. Lots of oomph there! Best regards, Raymond |

Best regards, Raymond Hi Raymond Have you tried a CCS under the 56s - I'm presuming these are a diff. pair? I use a Morgan Jones design from his Valve Amplifiers book. Basically two BC549, two red LEDs, a sense resistor and if I have any a J511 or if not a 1K resistor to earth. This may help get a good balance on the diff pair. I've used the LL1660 and it's fine, also used LL1635, LL1621, LL1671. I'm very curious about the cheap Edcor interstages - I'd guess they have better bass - and a few people seem to like them. Have you looked into those? They come in two sizes, and the values to try are probably 10k-10k or 15k-15k. Andy |

I'm using an input transformer for some extra gain (a Newcomb, I don't have the model # with me) ahead of the volume control, the wiper of which feeds the 56 grid. I'm using the 124B to feed the grids of the 71As with the CT grounded. Really simple circuit and it sounds very good in the mids and highs, but I'd like some more in the lower end. This would be a very good treble amp for bi-amping. I'm not familiar with the Edcor ITs. Thanks for the tip. I'll google them. Best regards, Raymond |

This may be the problem - surely the 124b isn't gapped for SE use? �I'm using the 124B to feed the grids of the 71As with the CT grounded I use it the other way round - CT to HT on the input, which is a diff pair with CCS. We may be getting different effects, plus mine steps down and yours steps up. Andy . |

I do like the step up though. Back to the drawing board! Thanks for your input. Best regards, Raymond |
