Most került hozzá ez a erősitő bekapcsol a gomb kéken vílágít de nem csinál semmit ha valakinek volna ötlete mit kelene meg nézni miért nem akar a relé meg húzni ami inditaná az erősitőt.

Sziasztok!
Egy Skoda Symphony tipusu autoradiot hoztak javitani. Sajnos, semmilyen eletjel nem lathato a keszuleken. A bekapcsolo/hangero gombja szet van hullva, pontosabban kukas, de ettol fuggetlenul tovabbra sem kapcsol be, nem vilagit rajta semmi sem.
Kerdeznem, hogy ennek a radionak auto nelkul is kellene valamit tevekenykednie, vagy teljesen "nema" az asztalon probalva?
Koszi!
Udv!

Üdv!
A szokásos "belefolyt valami" hibaüzenettel kaptam az erősítőt; ellenállások meg néhány apróság elégtek, eddig semmi komoly, de a gyártó volt oly kedves és levakarta a TO3-as tokokról a feliratot. Meg tudná-e valaki mondani, hogy milyen végtranzisztorral szerelték ezt az erősítőt? Esetleg tegyek bele MJ15003-akat?
Köszönöm!

I am repairing a Dynacord Powermate 1000-2 mixer/amp and have a question about DC blocking capacitors in the signal path.
I am getting a slowly dropping DC on the DISP1 node (output of I6AA op-amp) on switch-on. This is causing the green "signal present" LED to come on on that channel which takes about 30 seconds to turn off. It seems to be caused by a charge on C35A that dissipates slowly through R54A (1M Ohm).
It seems to me, it would have been better to put the C35A on the output of I5AA with a resistor to ground. Is there a reason why this would not work.
I have checked all relevant components and power supplies and I cannot find any faults but I'm sure this is not normal behaviour.
Any help greatly appreciated.
