[Amps] One PS, many amps

["David G4FTC" <g4ftc@hotmail.com>]

I?m wondering if for triode amps the solution may be simply to isolate the 
DC path from the grid to the chassis of each amp so as to prevent one amp 
affecting the meter readings of another amp.

See my sketch at http://www.qsl.net/g4ftc/amplifiers/multiamp/multiamp.jpg

The decoupling ?C? will provide the RF return paths for the input and output 
but provide the DC isolation.

My concern in using a single PSU in a multi-multi contest station would be 
that should a glitch occur in one amp, then the protection circuit in 
shutting down the PSU would effectively take the whole station off the air.
