Pošto bih jednoga dana verovatno i pravio F40, voleo bih, ako može i predlog napajanja . Po mojoj računici, to bi bilo oko +/- 50V al ipak bih, ako može, i shemu nečega što bi se moglo smatrati vrhunskim napajanjem za taj amp.

Da li se možda razmatralo i dedicated switching power supply. I u teoriji i u praksi, vrhunski projektovano prekidačko napajanje trebalo bi i da je bolje od klasičnog. Možda je (tehnološki) suviše nova teritorija...

Na semi F40 kao i A40, A33, A23... napajanje VAS-a je preko otpornika 10 oma sa na napajanja izlaznog stepena. Namerno sam tako nacrtao zato sto vecina ljudi u samogradnji za napajanje pojacala korist samo grec i dva elektrolita. Najbolje bi bilo koristiti posebno stabilisano napajanje za VAS kao sto je PSU60.

Imam i SMPS napajanje, ali ga ipak preporucujem za PA pojacala.
