Hello everyone!

I'm a newbie here, and have been visiting this forum now and then and i finally decided to login

I have a question about miniature russian tubes:
I bought some 1SH24B, 1SH29B and 1P24B tubes, made a small design using the extremely low power 1sh24b and a FET for impedance matching, but it didn't work (strangely, reversing G2 and G3 connections, it seemed to have more output volume).

Any ideas on a simple circuit that uses these tubes, preferably low B+, for driving 2 louspeakers?
I don't know much about tube design, honestly

Many thanks fellas!
