This post was made in the effort to offer the recording community some
new Telefunken U47M & U48M microphones. It was not intended to start a string of childs play. However there are always a few bad apples in the bunch. Telefunken North America is the only microphone company that still manufactures orginal classic europan microphones that are exact in every way. We have a few TEC Awards & Nominations under our belt so we must be doing something right? Our products are in the hands of 100's of well known artist, producers & engineers. So if you have a problem with our politics, why do you go back to the rock you climed out from under. I'd like to know what you have done to help this community? Or do you just try to upset others? Oh ya, are you such a spineless wimp that you wont give us your real name!? If anyone here is a f8ckwad it's you........ Kind Regard, Toni Fishman CEO TelefunkenUSA I do, f8ckwad. When I buy an EH, I want EH, not crap from a ****head who bought a name. If these folks are so hot, why do they need a bought name for clout?

I reckon you must be a noob. I can't recall ever having been so supportive of a person, his company, and his product and having received so thorough a flaming for having done so. I'll grant, Mr. Fishman, that reading comprehension is not necessarily a skill one might require for the production of high-quality microphones. On the other hand, in this case it has evidently proven important within the sphere of online business relationships, and your lack thereof has put you in the rather puzzling position of having offended the one poster on this NG who has (so far) shined a positive light on your endeavors, and further of having offended one of the people most likely to have the connections necessary to put you in touch with persons who might supply you with the rare tubes you're looking for.

It's a sad day indeed when the CEO of an audio gear manufacturing company is so lacking in basic English language skills as to imagine he's been insulted by someone who was handing him an *exceedingly* rare Lord Valve Attaboy. You stupid ****ing putz. You ignoramus. You dolt. You stinking mouldering piece of excrement. You tonedeaf sleazebag - may you spend the rest of your days recording street rappers with a Mister Microphone plugged into a K-mart ghetto blaster. Do yourself (and your company) a big favor, you ignorant ****, and have someone (your secretary, perhaps?) read this entire thread so he/she can explain to you exactly how full of **** you are.

I'm not LV but I don't believe his specific expertise is required to get you
on the correct track regarding your Bogen Challenger. Bob Hedberg's response way above is pretty much on the mark AFAICT; Filter caps downstream of the rectifier tubes are probably shorted and need replacing. You pretty much verify this with your subsequent post stating that no fuses blow when the rectifiers are out of their sockets. When you get past this issue you might also consider running the specified 5Y3 rectifiers instead of the 5V4s unless you also modify the PS and/or output stage bias. Why??? The indirectly heated 5V4 has roughly 1/2 the voltage drop at load as does the directly heated 5Y3. This MAY result in continuous DC voltages ~25 or more volts above design. Combine this with the fact that mains voltages are 120VAC in most parts of the US when the amp was probably designed for 117 and you're probably on or over the edge of filter cap continuous voltage ratings and maybe even output tube ratings Good luck. Oh... and Lord, please forgive me for buttin in on your traffic. -- Steve "Bro. Yahya" wrote in message m... HEY L.V.! Its been a minute. Guess i haven't missed much huh?!?

What does any of this have to do with the proliferation of scumbags grave-robbing brand names & sticking them on their (possibly good) forgeries (err... copies?)? A brand name is a commodity which can be bought or sold like any other. While the logo may get one's foot in the door (so to speak) the product will have to sink or swim on its own merits - like any other. If it sucks, the company goes broke, and deservedly so. If it has a good price/performance ratio and enough people find out about it, it'll fly in the marketplace. Mullard (for instance) made plenty of ****ty tubes in their day, and their badge on the glass is *not* an automatic guarantee that what's *inside* the glass is kickass. That's why I made the crack about listening to logos - brand names really aren't anything to worry about, except from a historical standpoint. And if someone resurrects a defunct one, so what? That's just more knowledge for afficionados in the field to impress the rubes with. So don't start squealing about Mike Matthews resurrecting the Tung-Sol and Mullard badges - his tubes will either rock or not rock, and the marketplace will tell the tale. (BTW - so far, they rock. Especially the new Tung-Sol 6550.) Want to buy some recently-discovered Picassos? That's a red herring, and you know it. Picasso was a single person, with a unique artistic concept. Tubes, mikes, cars and whatnot are assembly-line products built by a multiplicity of persons with diverse talents and skills. Lord Valve Asshole |

I wonder if you'd drive a porsche if some Connecticut mechanic licensed the
name and started making ca.1960's 911's and calling them porsche. Especially if his parts usage deprived owners of the genuine article access to supplies. The only thing that Mr. Fishman has going for him is that Telefunken never manufactured anything, and that the actual mics that he makes are copies of the ones Telefunken bought from Neumann and AKG. Judging by his mischaracterization of LV's posts, it is clear that Mr. Fishman is not the sharpest knife in the drawer. Telefunken USA, puh-lease. In NYC, the Ray's pizza people solved their issues with authenticity by calling their copycat company "Original Rays", which was followed by "Famous Original Ray's", then Original Famous Rays"... I'm not critiquing the mics- I've only heard them at a trade show. I m critiquing the idea that he has to claim that they are "the same as the originals in every way." The idea is such bull****, whether they perform as such or not. It seems like TF has too much money and not enough originaliy to design and market his own product... Andy T NYC |

You pretty much verify this with your subsequent post stating that no fuses blow when the rectifiers are out of their sockets. I will second this, and I will also say that that metal can cap on the Challenger is very, very badly chosen. It's just on the ragged edge of the voltage rating when the amp is operating, and it's well over the rating when it powers up. It must be replaced. It's also possible that the output tubes are shorted too. I'd suggest that you try firing the thing up with the output tubes removed, but this will definitely run the supply caps way over their rated voltage. When you get past this issue you might also consider running the specified 5Y3 rectifiers instead of the 5V4s unless you also modify the PS and/or output stage bias. Why??? The indirectly heated 5V4 has roughly 1/2 the voltage drop at load as does the directly heated 5Y3. This MAY result in continuous DC voltages ~25 or more volts above design. Combine this with the fact that mains voltages are 120VAC in most parts of the US when the amp was probably designed for 117 and you're probably on or over the edge of filter cap continuous voltage ratings and maybe even output tube ratings I strongly recommend modifying the power supply. The amps were designed to be as cheap as possible for the lowest grade voice applications. The power supply is undersized and the caps are on the verge of failing. If you put modern solid state rectification in there and modern caps, you will get both a much stiffer supply and a much higher voltage supply. And yes, you will have to rebias the output stage! We used to use those as studio talkback amps when I was first starting out. We'd also change the output tubes for something a little higher current too. Problem is that there is not much room in there... a 7027 (which was the cheap super-6L6 replacement at the time) is way too tall and I think the modern Sovtek 6881WXGT tubes are just as bad. Oh... and Lord, please forgive me for buttin in on your traffic. What was the original post about and how did it come to be crossposted into r.a.p. anway? --scott -- "C'est un Nagra.

So if they are built using the same materials to the same specs they cannot be the same? What is the deciding factor for your claim? Must the materials used be 40 years old and only assembled in germany? How about the new WE 300Bs? You can still buy a new Delorean today even though the company is finished. They use a warehouse full of spare parts. Is that any different from one made 20 years ago? Obviously there is a market for new Telefunken mics, otherwise this guy would not be in business. With the prices people pay for VF14 tubes someone should be able to get a company like Valve Art or KR to make new VF14s. But oh wait they can never be the same. Adam |

Adam To quote a nameless friend: Now he (tony fishman) is in the process of spending double on all the available stocks of good microphone tubes (AC701k, VF14M, 6072A M, etc.) which will leave the rest of us who actually use this **** really screwed. Personally I don't see the need for someone to be manufacturing U47 microphones again. The fact is that the M7 (and for that matter the CK12) capsule was difficult to consistently manufacture for the largest of European manufactures with the best hand assemblers in the history of microphone manufacturing. So are we to believe that Telefunken USA a tiny company in CT is making exactly the same mics?? Even if they can, what is the sense in making microphones that use an obsolete and impossible to find tube....especially if you are going to sell it for more than the vintage mics on the market. If you are curious about how little this guy actually knows about sound and engineering consider this....he will sell you one of his prized U47M microphones (for $5,500) with a nuvistor! I don't know one serious microphone builder or tech who thinks the nuvistor sub that Neumann offered as a last ditch solution to dwindling VF14 supplies was a good idea. Especially since the output transformer on this mic was specifically designed around the VF14 (quite an unusual tube) which has nothing in common with 13 CW 4 Nuvistor. Perhaps I would be more intrigued by Telefunken USA if they designed something new that built a reputation based on how good it sounds instead of resting in the fact that most buyers listen with there eyes and base their decisions on brand recognition. |

It's just on the ragged edge of the voltage rating when the amp is operating, and it's well over the rating when it powers up. It must be replaced. It's also possible that the output tubes are shorted too. I'd suggest that you try firing the thing up with the output tubes removed, but this will definitely run the supply caps way over their rated voltage. When you get past this issue you might also consider running the specified 5Y3 rectifiers instead of the 5V4s unless you also modify the PS and/or output stage bias. Why??? The indirectly heated 5V4 has roughly 1/2 the voltage drop at load as does the directly heated 5Y3. This MAY result in continuous DC voltages ~25 or more volts above design. Combine this with the fact that mains voltages are 120VAC in most parts of the US when the amp was probably designed for 117 and you're probably on or over the edge of filter cap continuous voltage ratings and maybe even output tube ratings I strongly recommend modifying the power supply. The amps were designed to be as cheap as possible for the lowest grade voice applications. The power supply is undersized and the caps are on the verge of failing. If you put modern solid state rectification in there and modern caps, you will get both a much stiffer supply and a much higher voltage supply. And yes, you will have to rebias the output stage! well i figured i'd have to do a cap job on it anyways but i didnt plan on changing over to solid state rectification. i only bought it becaus eit was cheap! i didnt want to throw a whole lotta work into it. it powers up fine without the rectifier tubes in. blows the fuse as soon as they're back in. turn it on, rectifiers glow red hot, then poof, the fuse blows. We used to use those as studio talkback amps when I was first starting out. We'd also change the output tubes for something a little higher current too. Problem is that there is not much room in there... a 7027 (which was the cheap super-6L6 replacement at the time) is way too tall and I think the modern Sovtek 6881WXGT tubes are just as bad. Oh... and Lord, please forgive me for buttin in on your traffic. What was the original post about and how did it come to be crossposted into r.a.p. anway? --scott i replaced the rect tubes today and changed the filter cap to a 16uf 450 volt. i could not find a 500 volt one. i hope this wont hurt the amp. i also changed the 6l6gb's with 6l6gc's i hope this wont do any harm either. i also change the 2 12ax7's. the amp fired right up. bit of a hum that doesnt go away when i turn the pots etc. its pretty contant. tubes break up around 5. not very loud either. i figure i should wire up 2- 8uf 250 volts caps in parallel and change all the other caps in the amp. the 6l6gc's have a bluish haze emmanating from them. i know a blue glow is normal. i have the amp wired to a 2 x 12 closed-back speaker cab. the speakers are rated 500 watts and 4 ohm. i wored them in series for 8 ohms. well...it sounds like an amp. i realize that this is a 50 year old amp in need of a complete cap job and its a P.A. amp so i didnt expect too much. i'm proud i was able to do it myself...with all of the wonderful help and suggestions from my friends here in the forum. i thought my wife would give me an attaboy but in retrospect she's probably ****ed she has to hear that damn guitar again! i would appreciate any suggestions on improving this amp and some changes to the tone circuit to improve the "guitar" tone. please post in layman's terms so i wont go "HUH"!! thanks It's not necessary to post your answer 4 times. I think we got it the first time. |

om... i replaced the rect tubes today and changed the filter cap to a 16uf 450 volt. i could not find a 500 volt one. i hope this wont hurt the amp. Buy or borrow a voltmeter and measure the voltage across that cap. If it's more than 450, that cap isn't long for this world. i also changed the 6l6gb's with 6l6gc's i hope this wont do any harm either. Shouldn't hurt. i also change the 2 12ax7's. the amp fired right up. bit of a hum that doesnt go away when i turn the pots etc. its pretty contant. tubes break up around 5. not very loud either. i figure i should wire up 2- 8uf 250 volts caps in parallel and change all the other caps in the amp. No; if you do that they'll blow up. You want to wire caps in series, with a voltage divider to put half of the voltage on the junction. Like this: ----|---------|---- | | cap resistor | | |---------| | | cap resistor | | ------------------- Putting caps in series like this doubles the effective voltage rating (so 250V caps will work up to 500V) but halves the capacitance (so two 8uF caps will become a 4uF composite cap, which will make the hum worse because it's too small). A couple of 100uF 450V caps in series ought to be nice and bomb-proof. Make the resistors 270k 2W and you should be okay. You can get the caps and resistors from www.digikey.com . Peace, Paul |

Digi-Key carries Panasonic caps up to 600V, although your capacitance values are limited. Replacing that 16 uF with a slightly higher value might not be a bad either. i also change the 2 12ax7's. the amp fired right up. bit of a hum that doesnt go away when i turn the pots etc. its pretty contant. tubes break up around 5. not very loud either. i figure i should wire up 2- 8uf 250 volts caps in parallel and change all the other caps in the amp.

If you absolutely HAVE to use metal can types, call Antique Electronics Supply in Arizona. Replace the paper caps in there with modern film capacitors if you want cleaner sound. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

Peace, Paul thanks paul there is a rectangular object 5000-7 R717A [resistor ?] attached to the cap. it started smoking today and now i get loud hum and motorboating. i dont have a clue. imeasured the dc across the cap and it was over 500. ill have to change that. when i turn the amp off the dc drops to zero. i understand the series / paralel thing now but being unversed in diagrams i dont understand the wiring or the resistors in your diagram. could you elaborate?'thanks for your help. |

That is a power resistor. It is smoking because something downstream from it is drawing way too much current. Probably this is because of a cap that is a short, or a tube stage that is misbiased due to a bad coupling cap. ALL of the electrolytics will be bad. Some of the paper caps will probably be bad too. imeasured the dc across the cap and it was over 500. ill have to change that. when i turn the amp off the dc drops to zero. i understand the series / paralel thing now but being unversed in diagrams i dont understand the wiring or the resistors in your diagram. could you elaborate?'thanks for your help. The capacitors are in series with one another, with a resistor in parallel with each one so they share load. But frankly, just buy a 600V capacitor. --scott -- "C'est un Nagra.

Hey, hotshot - these folks (Telefunken USA) make some *seriously* good ****. You got a problem with that? LV I do, f8ckwad. When I buy an EH, I want EH, not crap from a ****head who bought a name. When I want a Telefunken, I want something more than a sleazy re-brand. If these folks are so hot, why do they need a bought name for clout? Benjamin Edison-Tesla (so you can take this to the bank), -An Iraqi I'm sure you have hands-on experience with this gear. Right? No, you're wrong. Haven't even tried the real thing. Given the clueless schmuck who runs the company, I'll still have to say they're excellent. I have lots of tube customers in the recording industry and I've only heard positive comments on them. Hey, when you buy a Jaguar, it's a Ford. Tough ****, eh? The only jag I had had a chev. smallblock & an auto tranny in it. Rust & primer. It was an ugly 75 xj, but the price was right. Headache of a car. To answer your question, though: I neither want nor can afford a new jag. What does any of this have to do with the proliferation of scumbags grave-robbing brand names & sticking them on their (possibly good) forgeries (err... copies?)? A brand name is a commodity which can be bought or sold like any other. I know, i know. It's legal. Everything's a comodity. Just a short while back, one could buy people. Or send an old chum a witty postacrd made out of skin o' Jew. One could still buy lawers, on off chance one gets the notion that a fancy law firm might do a better job than a court-appointed shmuck, and has the $$$$$ to act on such a notion. That I did. Amazing how well it worked. Lucky me! OTOH, there are lunatics who question the ethics of all of the above, claiming that "just 'coz it ain't against the law, it ain't necessarily *right*". And folks with bux are buying great brand names. Wise, i think, at least from the commercial standpoint. One never went broke banking on the stupidity of the American public (a quote attributed to too many people, E.T.B. being the likely wit). In kase of Telefunken (of North America, or whatever), though, I'd do things a bit differently. I'd buy up an overstock of some crappy mikes, make molds / dies of old Telefunken mikes, send those off to a Taiwaneese / Chineese jobber, and stick the crap mike carts into the bodies. Then I'd be able to sell you a Telefunken for a couple 'o hundred $'s (assuming you were runnin' a studio - I wouldn't be foolin' *you*), and you can add a slew of "TELEFUNKEN MICS" to your studio's gear list. That would *certainly* get a few more "feet in [your] door! And, considerin' the fact that most players are clueless when it comes to studio gear, and rely on brand names tossed about by their buddies, you'll do well for quite a while. Neat, huh? While the logo may get one's foot in the door (so to speak) the product will have to sink or swim on its own merits - like any other. If it sucks, the company goes broke, and deservedly so. If it has a good price/performance ratio and enough people find out about it, it'll fly in the marketplace. So, you don't feel there is an intent to decieve when a well-known & respected brand name is attached to a product which looks a whole bunch like the brandname's well-respected product? Does the fact that $$$$$$$ changed hands make it less sleazy? Mullard (for instance) made plenty of ****ty tubes in their day, and their badge on the glass is *not* an automatic guarantee that what's *inside* the glass is kickass. That's why I made the crack about listening to logos - brand names really aren't anything to worry about, except from a historical standpoint. You betcha. People want the magic & history which goes along with the mike. Many "kit" (AC) Cobras can blow doors on the originals, but ... I'll take an original any day. If only to sell it again. And if someone resurrects a defunct one, so what? That's just more knowledge for afficionados in the field to impress the rubes with. And just one more way fore some scammer to dupe "rubes". So don't start squealing No, no, LV, I'm just typing. On an old keyboard named "Quiet Key". I love the thing 'cos it makes satisfying clatter when I type. hadn't squealed in a 'coon's age - had little reason to. about Mike Matthews resurrecting the Tung-Sol and Mullard badges - his tubes will either rock or not rock, and the marketplace will tell the tale. (BTW - so far, they rock. Especially the new Tung-Sol 6550.) Good for Mike. As far as toobs rocking or sucking, the "rubes" (golden-ears and pro players among them) usually can't tell the difference 'tween an oboe and a fart, so the "general consensus" is, pretty much, generated by "cognnoscenti" like yourself, parroted over and over by "rubes" as personal preferance or even fact. Truth be told, other than some tubes being *objectively* crappy (poor mechanical construction, high failure rate, inability to stand up to voltage ratings, missing the curves by a mile, etc., etc.), it's hard to tell the difference 'tween **** and Shinola in most applications. As far's 6550's, I wish someone would make a copy of those short-bulb 6550's - those things fit well... Want to buy some recently-discovered Picassos? That's a red herring, and you know it. Picasso was a single person, with a unique artistic concept. Tubes, mikes, cars and whatnot are assembly-line products built by a multiplicity of persons with diverse talents and skills. Hey, by signing a piece "Picasso", a forger simply gets his foot in the door - from that point on, his works sink or swim on their own merit, as you put it. Or ... do they? I figgah' they don't, 'cos the same pieces which the art critics were drooling over suddenly became worthless, and curators for bigass museums got to feel mighty sheepish.... So, i figgah', the lable added *something* to their artistic worth... (there's the rube thing rearin' it's ugly head again). Lord Valve Asshole -dim neon sign mover / network tech (today) |
