Cousin Billy-Question. Is the 2A3, 45, etc. a gain stage?
- In conventional SET amplifiers 2A3 ,45 ,and similar output power triodes connected as anode follower gains both voltage and current gain , resulting in specific output power gain ,
however those SET amps usually needs at least one more voltage gain stage to work properly , since voltage gain only from those output power triode tubes is not enough to interface with low level signals coming from standard sources , as CD player , pre-amp ,PC card , etc ,....-Could a 6SN7 be replaced in one of Ralphs amps by a 2A3? (I know there's wayyyyyy more to it then that, but in theory, could it be done?)
- No

BTW ,
in some way all Atma-Sphere OTL power amps can be considered as two same SET-OTL power amp units joined together forming unique OTL Circlotron Push-Pull balanced power amplifier unit .
