PUSH-PULL, no cathode follower ?

[Colas LeGrippa]

I am modifying a  50 w amplifier with no tone stack. I was wandering if I could skip the cathode follower and send the signal straight to the PI, from the preamp tube. Would that be a heavy load on the preamp tube ( s ) ?  I couldn't find no schem of PP amp with no CF.

Thanx

I couldn't find no schem of PP amp with no CF.

Fender BF AB763 (and silver face models) TS has no CF. It's plate driven.

You can feed the PI with a coupling cap from the plate of the preamp tube, but it might not have enough drive signal. I think you need at least 2 triode gain stages.

Check the AC30 normal channel schematic (no tone stack) & you're done...

PP amps require more signal voltage than a SE ( like the Fender Champ ? )

yes, you can. will you have enough drive swing? that's another question and requires schematic with telemetry to answer with reasonable accuracy.
