It seems to me that the output stage is broken. How could I proceed if
I don't find the service manual?


Before doing anything else, check the rear panel for a set of loop thru'
connectors for going out to a sound processor of some description. They are
usually 4 x RCA phono type sockets, and may be marked either "Processor" or
"Pre out - Main in" or something very similar. There is often a thick bar
silk-screened between them to indicate that they should be linked. Very
often, an amplifier will arrive on the bench with exactly the symptoms you
describe, and the original factory-fitted linking bars missing. Usually, the
person is a 'new' owner who has picked the item up second hand, and doesn't
realise that the sockets need to be linked. If you find it to be the case on
this one, all you need is a short stereo RCA to RCA lead, to patch them back
together.

Thank you for your quick reply.

Your guess was indeed spot on. It works very well now

Now there is two smaller problems. First the balance controller is
noisy. I'm going to try to clean/replace/bypass it. The phono input,
however, gives a large amount of noise out even with volume turned way
down and nothing connected to the input. I guess this means that the
phono preamp is broken. Would just disconnecting the preamp circuit be
a reasonable course of action?

Thanks again for the quick and precise answer. It saved me a lot of
time!
