Sziasztok!
Az erősítőbe felcseréltem a végfokokat, a hiba átment a másik oldalra. A hibridet kibontottam, mikroszkóp és röntgen alatt sem látszik rajta semmi. Gondolom valamelyik félvezető.
Van valakinek egy ilyen modulja a fiók mélyén? Esetleg valami +/-40V-os tápfeszültségű végfokmodul, amit be lehetne tenni?
Üdv. Jácint
Tanacsra lenne szuksegem. Gyanum szerint a bemenet valasztoban lehet kontakt problema mert bizonyos bemenetknel neha recseg a bal oldala. Tobbnyire ha nagyon halk resz van a zeneben fuggetlenul a hangero potmeter allasatol. Ha befujom kontakt tisztitoval akkor a problema megoldodik par hetig. Letezik valami hosszu tavu megoldas? Meg nem mertem szetbontani magat a kapcsolot.
Koszi a segitseget elore is.
Udv
