Derűs napot kívánok!
A fenti autóerősítővel küzdök Az egyik végfokban mindkét FET valamint a tápban két FET csont zárlatos volt. Ezek cseréje után elindul, de folyamatosan nő az áramfelvétele, amíg hagyom. Kivettem mindkét csatorna végfok FET-et. A táp alap áramfelvétele 12V-ról közel 800mA. Szerintem ez elég sok. A táp +30V/-28V. Ez az aszimmetria sem tetszik nekem. Hidegen mérve minden jónak tűnik. A szabályzás is érdekesen működik, mert ha leterhelem egy 230V-os izzóval a +30V-os ágat, akkor a vezérlőjel impulzusszélessége megnő. Ez csak a +30V-os ágra igaz. Ha a -28V-ot terhelem, akkor leesik a feszültség -26V-ra és nem szabályoz a táp. Jól jönne, ha kitudna valaki segíteni egy rajzzal. Köszönöm.
Üdv.
I have just completed a brand new manual for this HiFi set.
I would like to add it to the library on this site.
How do I do that?

Wim
