Some amp (like the VOX AC30CC2) use a circuit like this to avoid Humm
(also Merlin on his books has a version of this circuit)

Here the Power Section of the AC30CC2

I'm seeking for other amp schematics that uses the same circuit

Plese, if you have a link share it

THANKS

Franco

PV did it on a few of their amps (Classic 30 etc). Fender did it on the 63 Reverb RI

In first post first example: could current flow from 35V to ground or from -35V to ground? I do not see a DC connection.

No. What do you mean by "DC connection"?
