Denon DRA-345R Tuner csak mono, 0.05 MHz freki eltolódás
Sziasztok!
Pár éve küzdök már a fenti rádió-erősítővel ami jól szól de a rádió része csak Mono, nem billen át Stereo-ba. Ez a nagyobbik gond, a kisebb hogy 91.1 MHz helyett 91.15 MHz-en van pl. a Rádió1 pozíciója.
Mellékelem a kapcs és a nyák rajzot. (később teszek fel fotót a panelról is)
Jól gondolom hogy a Stereo problémát esetleg a T603 és/vagy a T604-el lehet orvosolni? IC-ken a lábfeszek rendben vannak.
A 0.05 MHz eltolódás javítására is kérnék 5letet.
Köszönettel:

Denon DRA-F107 - Dead, no power
Hi to all. Unit arrived dead with no power. The problem is with switching power supply. I checked most of the parts, no faulty found. Unable to check PWM ICs. To determine which one has the problem, Service Manual is more than important and necessary. I would appreciate if someone of you can help me find it or send it to me. Thanks in advance for your kind attention and help. Regards from Greece, John
