Helló!
Arra gondoltam, hogy felveszem mp3-ra és arról táplálom meg a végfokot, így könnyebb megnézni hol kezd e l torzulni a jel.

Üdvözletem tisztelt Mesterek.Egyre többen érdeklődnek hogy gyári CD tár helyett lehet e USB vagy SD kártyát csatlakoztatni vagy mi a megoldás?Már láttam ilyen gépt,de én balga az ügyfél számát elveszítettem.Sokan a gyári gépet nem akarják cserélni, de a kazetta már elavút , a CD tár meg 50-100 Ez.Ft. És mindig csak CD. Amit említettem az SD-kártyás volt. Öreg Tom
Want to share:
Have downloaded the schematics from this forum to help repair the amplifier of a friend.
Turned out that Sony decided to route the earth through the chassis, even the earth between the various supplies.
When one takes the main board out of the chassis and switches the amp on, there are up to 20 volts difference between the eart (and hence reference) of the pre-amps and the main amps.
Luckily the amp goes into protection but from a design point of view it is not nice to rely on screws and aluminum face plates to conduct up to 0.2 amps of current from one supply to another.
What I did is solder wires to every eart point and connected them on the main board to make it stand alone and not rely on conducting current through the chassis anymore.
Bad design, simple repair but took some digging in the schematics to find out what exactly was going on!
Sziasztok!
A fenti erősítő kapcsolási rajzát keresem, aki tud segítsen.
Előre is köszönöm. További szép napot mindenkinek.
