Another NOS tube that is getting harder to find every year. Electrically equivalent to EF86, but octal based. Ideal microphone or pre-amp tube, because of metal shielding, and low noise. Come out of the boxes like new. |

Lovely made smoked glass 6V6, with hand-blown tube base. So no machine made tube. Printed 6N6c, which is Russian for 6V6, they used other letters. This tube is basically the older octal version of the EL84. Use any EL84 schematic to make your own 6V6 amplifier, but also many 6V6 schematics are around. Why fight over the last remaining pieces of NOS EL84, while you can get this beautiful made version of this NOS 6V6 tube. Original colored boxes. |

12GN7A (12HG7)

1980's |
11.5 Watt. Potential Audio type. Can be wired for 6,3V or 12V. Nice as driver tube with Lundahl LL1660 interstage. Optically like a 6H30 , but 12GN7A is a pentode. Probably triode connected it will give a great triode. Secret tip? |

VERY SPECIAL TUBE. A real three grid pentode, no beam pentode like 6L6 or KT66. Can be seen as a kind of (better!) EL34, but with another socket and top cap. Electrically comparable, and can be fitted in most EL34 circuits, but it may need some minimal tuning to get the correct bias. So not fully identical. When looking inside, with a magnifier lens, I see the huge, flat cathode and.... clearly visible is the GOLD control grid. This is finest quality, it has lower distortion then normal EL34. The first grid is yellow color, second grid is gray, and third gird is white nickel color. So yes it's a gold grid version. Very potential audio tube. The schematic given here, shows 64 Watt in Push Pull.
NOS black material Sockets are available, or gold plated Ceramic sockets from Yamamoto Japan.

C3g C3m info. Important. |
|
I had an excellent contact who digged up C3g and C3m tubes, by contacting the original buyers. And yes, he was lucky several times to find old stock that way. He told me there is really nothing left to find any more at OEM customers, not at the post, not at others, just nowhere at all. So what I did, I bought all C3g and C3m he had. They were many, on wooden palettes. Too much for myself actually. They greater part of those went to amplifier manufacturers, and I kept some smaller stock for myself. So what we have for sale here is a depleting stock, and prices (as always) rise fast after the last tubes are gone. |

As tube buyer sometimes have a lucky day. Like this one here.... Out of the box came came one the nicest C3g versions I have ever seen, and the Lorenz (Stuttgart, Germany) brand has an excellent reputation. The tubes are individual numbered on the tube top, and have a nice, blue paper roll on it. They come out of the boxes crispy and new, as made just yesterday.

 D3a Siemens
Order Number:
114-113-85
|

This is another fabulous tube, like C3m, C3g, etc. It can be used pentode or triode mode. Triple Mica Version, gold pins. These are from a lot made by AEG Telefunken ULM, for Siemens. I can tell because I bought this lot directly as surplus. I have those in original sealed 100 pcs. master cartons. Each tube individually boxed. This is a FRAME GRID pentode. Extremely rare with tubes. So use it as a very high gain pentode, ideal for Moving Coil amplifier, or others that need lowest noise. Yet it can do high voltage as well. I have even seen it as current source in a mu stage, very successfully.
  
Normally, a pentode if connected as a triode will have unlinear curves, so they are not made for that. Not so with D3a! Truly amazing, excellent original triode curves are published. When you choose the recommended operating point, the curves are very linar, and in triode mode this tube has a gain of 77x. How about that gain?! From the family of ECCxx tubes, I only find ECC83 which can do so, but ECC83 is very high impedance, and ECC83 gold pin NOS is expensive. D3a will give a gain of 77 at much lower impedance. So you see, this tube is really a first class product.
  
D3a had a factory price of 286DM one. That is 145 Euro. The factory was EAG Telefunken, and production was by them for Siemens. It was the most expensive small signal tube they made.

Packed in original bag. Beautiful Gold pin tube, also perfect in triode mode. Triode gain is 50, and Rp =2k3. For this price you can't go wrong! 3 Watt tube, wide wite flat cathode, for superb best linearity. SQ 10000h tubes, very tight to the specifications. Philips datasheet here .

Tesla NOS tubes have been a forgotten treasure for a long time. Well, these days are gone. It is so funny to see how the old story repeats over and over again. When you can buy them in quantities, nobody wants them, and when they're gone, everybody must have them. I remember I could buy TESLA KT88 for only 20€, right from the factory. And nobody was really interested. (Oh, it's only Tesla.. well, I can buy them another time.... That kind of talk). Now they're gone, I get still get requests from people who remember it from 10 years ago, that I had them. Only unfortunately nobody has them for sale, not even for 100€ each. The intermediate period, when they change from normally available to unavailable is always very short. So this is standard behavior for the NOS market, and I am convinced this will never change.
With ALL TESLA small signal tubes, like E88CC, or EF86, EF806S, etc, etc, we are now in the transition period (from available to unavailable). Please read the above short story again, to know what the really means.
Collectors start now t buying those TESLA EF806S, which is identical to TFK EF806S, and Ultra High quality tube, low noise long life version, to replace EF86.
With Original box. You Must read the data sheet for details, it an amazing data sheet It is the same series of ultimate tubes: ECC801S, ECC802S, ECC803S and EF806S. This is probably the best EF 86 in the world. These tubes have Rhodium plated pins. Rhodium is in the family of "hard-metals", same as Molybdenum, or Tungsten. So it won't come off. Rhodium has perfect contact properties, better than gold. (It is more expensive than gold also)
Tubes are in original Blue-Yellow Tesla boxes, with a quality stamp on the inside flap.

I was lucky to find a smal lot of those, individually boxed. The Svetlana factory went through a hard time, struggling against New Sensor, who had aquired their brand name. They went almost bankrupt from this. Personally I would not want to buy any tubes from that period. I estimate the hardest years were around 2006. We must say they seem to have recovered. The tubes from BEFORE the trouble are regareded by some the best EL34 ever build. Silently and secretly they had things perfectly under control. Datecode and Winged =C= are on the glass with gold metalized print, this can't be faked. Just do a search in the pdf pricelist for "winged".
The newer versions (that are not for sale here) have "Winged =C= SED" on it. The older ones have not SED on the boxes or the tubes.

You like "another" tube than KT88.... try GU50 (similar to EL152).
This is a big, 55 Watt tube. (Full data sheet here). Good printing, original box. Absolutely excellent Audio tube. Military NOS quality, no commercial tube like KT88.
PICTURES + SCHEMATICS HERE
WE SELL THE SOCKET FOR THIS TUBE ALSO.
They're lower cost and compared to GU50, KT88 is only a consumer tube. GU50 is extremely strong and very low distortion. Amazing quality Russian military old stock.
Note: These can not directly replace KT88, because the bias setting is another, and also the sockets are another type. We can not help you with modifications, specially not when you have no idea how to do it. We can only give you the data sheet, and for if you know yourself how to do this. Well, it is easy to do for a specialist.
The bulb is hard glass. It has Four (!) getters, and inside made from hard metal. You can hammer a nail in the wall with this tube. Much different from the fragile KT88. The metal piece can be removed from the top, using a hot air gun, like you use for hair drying. Bake the top, and the glue will get soft then, and brittle away. The bakelit tops you can srew off, and are even nice feet for a small amplifier, no joke, these are lovely made.
Excellent Triode curves. Similar to AD1 or RE604. Not the same, but bias is comparable. What else do you need as a secret tip :) |
