Hello to everybody.

I would want to use a pair or quad tetrode (4-400a or 4cx250/350) as GG
triode for AB/C class operations.

I don't remember where I have read that only the control grid had
physically push to ground, while the others grid(s) was electrically
floating and connected to ground through of the capacitors....

Can you help me with schemas, links and suggestions?

Many thanks in advance..and sorry for bandwidht...
