Default Onkyo P3060R Preamp: ISO SM

I just received a ~1983 Onkyo Preamp P3060R that i want to use as a phono preamp mainly. I opened it up to find out if there's any work to be done, but mostly it's just cleaning switches and repairing a very hummy Phono in#2.
It's nicely built, a lot of Alps and massive ground wirings, but in both phono pre and output stage i saw 4558 opamps. I have no clue if they're in the signal or not as the onkyo features capsuled modules (like the marantz HDAM) in each stage....

I easily found manuals online, but

DOES ANYONE HAVE A SERVICE MANUAL for the P3060R?

I'd be very thankful.

Regards,
Matthias

by the way, are you sure you have the 3060R, and not the 306R? i've seen modules in the 306 but don't remember about the 3060R ...

I'd be great if you could find the sm @ home. I took a closer look now, the input switches seem to be worked on with "kontakt60", which is a slightly corrosive contact spray
Someone obviously threw out the phono caps right behind the plugs and phono #2 had no ground connection... but now everything important works except lots of dead lamps behind the front plate. The mode switch is still a mess, only normal operation works. Obviously unused for a long long time....

BTW mine looks like this:

Hey thanks for looking!

In the meantime ordered a copy at "schaltungsdienst.de" (they send you prints). They somehow had two p3060r in their catalogue - hopefully i get the correct one Should be here tomorrow!

Take care,
Matthias

Jesper,

if you don't receive a pdf copy in a couple of days, let me know. As stated above - i own a paper print of it, but never took the time to scan ~16 pages, partly in A3.

I am looking for a volume knob for a P-3060 that I bought when I was in the Army while being stationed in Germany.

Does anyone have an idea where I might get one?

Regartds,
