Sziasztok !
Szeretnék segítséget kérni, hogy pontosan mi a menete a képen látható AVA Model 2A végfok beállításának, a végfok csövek 2-2 db párhuzamosan push pullba kapcsolt EL84, a katód áram a gyártó ajánlása szerint 30 mA. Gondolom az egyik potival a negatív elő feszültség nagyságát állítom a másikkal pedig a két oldal szimetriáját lehet beállítani. Ez a 30mA csövenként vagy oldalanként értendő. Illetve mi a beállítás pontos menete ?
Előre is köszönöm a válaszokat.
Üdv:
Antal

Friends Sony STR DH130 goes into protection mode soon after turning on. It works for a second then can hear loud pops from speakers.
I've tried the suggested methods to fix but nothing works. Correct impedance speakers. Speakers wired correct. Good ventilation.
I've tested the output transistors in circuit and I don't see anything unusual. I may pull them to test but will wait for advice here. I also measure
about 57 volts on the emitter resistors. Seems high to me. Anyone?
