837 tube

[Simeon Petkov]

Hi.
Anybody heard of this tube- 837 ?
Any data in triode mode ?
It is beautiful. The anode is big and looks like 811's. It has two cathodes and a nasty socket.
My pair is russian G-837 from 1963.

Best wishes,
Simeon Petkov

Oh, thanks.

Only 12 watts ???
WTF, it has 811's plate and it is rated at only 12 watts ???
Well, if i try it out, i will load it with at least 25 watts.
Here they are cheap.

Thank you !

Don't they have same pinout as American 837?

Probably. 807 is a beam power tube while 837 is a true pentode. It is like comparing a 6V6 to a 6F6.
