Prevyot,
sorry I'm not so fluent on russian but feel free to answer so I can understand a lot.
Got myself 2x GU-5b tubes, along with 12,6V/30A for heating, and 3,6kV/1,2A transformer, and I'm planning to build amplifier with 1x Gu-5b.
Since there isn't a lot info I would like to know - does anyone knows what is gain in db of the triode when used as grounded grid amplifier?
