Tube equal to one section of a 12AX7?

[Pyre]

They must have it wrong or something.

That is a pretty interesting tube. have you ever used them in anything? How did it sound if so.

12 pin socket, is that the same as the old plug in relays used?

I have used:
6FM7
6FY7
6FJ7

I plan to implement a 6U10 as a single tube Mullard phase splitter in an upcoming project. These are some of the last American made tubes, and IMO are quite excellent, especially at the price. The only problem with them is trying to get people not to throw them in the trash.

Also, 6C10's and 6D10's can be a little expensive here and there, but I bet you can find some pretty cheap pretty easily.

6C10s are nearing extinction. They are used in some older guitar amps (Ampegs IIRC) and they have been pretty well used up.

The 6AC10 is a much more common and available cheap triple triode, but it's not 3 12AX7 equivalents.

Hello Pyre

The 6AV6 has two diodes, pins 5 and 6 with pin 2 serving as a common cathode, shared with the triode section. Ground pins 5 and 6.
AES may have some 12AV6's cheap and you'll be all 12.6V filament-wise!
I've never been a fan of these tubes but they should be ok in the CF position.

I'm back!

Thanks

The Russian 6N2P is basically the same as a 12AX7, except for a different pin arrangement (6.3V heater only). Obviously they have two triodes inside, but they are very, very cheap!
