    Hallo guys,

    Does anybody have some more technical info on this Technics amplifier
    from the 80's. I already have the schematics but I am looking for more
    detailed information, if possible, to fix an old amplifier.

    Thanks a lot.

    Hi The manual won't give you any better help ~I'm afraid
    the problems on this model usually are around the AN7062 and
    Q501/2/3/4. its not often the main SVI fails (luckily)
    the transistors above run very hot and will go leaky, there are also a
    couple of 47 or 220 ohm resistors nearby which also burn out
    What info do you have about the fault?
