Ako je tu nestabilnost pojacavaca resio sa dodavanjem dodatnih kondeznatora na railove napajanja onda je definitivno merenje radio sa opterecenjem jer drugacije nebi mogla da mu se primeti takva pojava jer nema protoka (neke vece) struje kroz rejlove napajanja.
Verovatno je imao problema sa PCB i rutiranjem visokostrujnih veza, posebno ako je imao vise parova izlaznih tranzistora i nije vodio racuna o tome.
U svakom slucaju tesiranje treba raditi sa opterecenjem jer svakako necemo da "slusamo" pojacalo bez prikljucenih zvucnika Wink
Moze bez zvucnika samo da se proveri da li je uopste OK pojacavac ali realni uslovi su ipak sa opterecenjem.
