LJM mentions it's OK to use less then +-60v rails and I've got an Onkyo adm21 that I was thinking on using the chassis, heatsink, and transformer. The transformer has 43-0-43, 33-0-33 (not used), 18-0-18, and 5vac. The schematic for this amp shows +-57.8 rails and it uses 2sc5200, 2sa1943 (just one of each for each channel.
Is the L20SE going to live with this much rail voltage?

I'd like to ask whether the CP1 22uF input capacitor is a part od the negative feedback circuit in those amps?

If the answer is yes, CP1 can't be shorted even if there is no Vdc at the input.

I think the answer is YES.
