Anyone made a 3cx800 conversion with Russian tubes & sockets? Or 4cx800 replace 3cx800?
One is a triode, the other is a tetrode. Different biasing and a grid supply are required, I believe.
Screen supply minor inconvenience vs $1600 of new 3CX800 if they can even be found. Or possible grounded screen?
The Russian GI-46B triode is likely the best to replace 3cx800. Anyone try this?
I think I’d rather walk on glass than to try and transplant GU74b tubes in place of 3cx800’s. That’s just me.
