I have and found most of the voltages as indicated on the circuit diagram, till op amp M 5218P; are near those specifed. The output on the centre of the two power transistors of both the channels are also alright.
While looking at the voltages on test points as mentioned on the page 7 for setting up quiscent current, these cannot be set.
Bit of history, the amplifier was lying unused for long time. Nothing in it has burnt. It was never opened earlier than this time, couple of days back.

While I was probing for voltages with DMM, with probe on collector of TR413 one of the fuses blew up. Later same thing happened on the other channel as well.
With the above as background can a Good Samaritan figure out feasibility of repair.

Hi!
Tudnátok segíteni?
Hoztak egy ilyet szíjkészlettel, hogy cseréljem ki. Kicseréltem, de nem nagyon akarja tekerni az első orsót, ill. gyors tekerésnél nem maradnak bent az előre hátra csévélő gombok. Mi lehet a bibi?
Kösz

Sziasztok!
A fenti típusú cd-s autó rádió bekapcsolásakor a kijelzőn a "----" jelenik meg és nem reagál egyik gombra sem.(nem engedi beírni a kódot). Hogy lehet ezt orvosolni?
Üdv.:Ckó
Üdv. Segítséget kérek! Egy sharp sx 8800 H erősítő hibás!
a hibája hogy van A+B oldal meg még 2 külön álló oldal
na most az A+B oldal úgy szól ha csak az A ra van kötve vagy csak a B re a kettő együtt nem szól
a külön álló oldal meg egyáltalán nem szól
ami okozhatja IC STK 4050 H 2DB van benne
meg egy tranzisztor de nem tudom kimérni őket mert nem tudom az értéket hogy mennyinek kell lenni-e
