Already bought it from
www.user-manuals.com .... like I said it has
schematics and parts list but is not very detailed on voltages.

I found a Pioneer A-X340 amp, it's a rather nice unit someone brought
from Europe and I'm trying to convert it to 110 volts. I was able to find
110-volt replacements for the transformers, but when powered the overload
protector prevents the speakers from energizing. The DC bias voltages are
way out of whack (+ or -40VDC on the bases of all 4 output transistors,
for example), but nothing appears to be shorted. For troubleshooting
purposes, I need to replace or at least substitute two preamp IC's
labeled PA0016. I found a service manual but it does not give a detailed
pinout of the IC or specify what voltages it should have on it. Nor can I
can't find any datasheets online, and I suspect the IC must have a more
standard equivalent.... but what is it?
Any advice would be much appreciated.
Hi Packrat...
Doesn't seem to be any schematics available for free; but if you're stuck
and have to pay, there's a .pdf available here for 15 bucks...

Take care.
