6J7 TUBE DRIVER

Last edited by Tom Phillips; at So, I decided to spring for some unused, old, RCA tubes, in their original boxes. I suppose the metal ones provide better shielding. I found the listed as a substitute for 6J7 in the Tube Substitution Handbook. The tube socket holds the valve in place and provides terminals, which can be soldered into the circuit for each of the pins.

Both listed as having the same basingso should be a drop in replacement. I think you should probably be able to find NOS. Maybe the tube looks tuge because the body is made of metal instead of glass. Dec Sat 29, 2: No Returns and no international shipping Thanks. Tubr the microphonics the same?

If you send me a box with the postage attached I’ll send you a few 6SJ7s to play with – this would be the easiest socket conversion – I probably have some 6J7s also.

I’m a little late here but I just stumbled into this discussion. Some tubes have top connections. JC, what about the top connection? Shall I put that metal cap on top of the EL36 too? I attach here a schematic of the preamp section, in case it helps.

And this is the tube schematic:. Carlo, if you are going to use an El 36 use a porcelain anode cap that’s safe.
