Pin 14 of IC703 connects to middle leg of Q801.
And yes, i am completly sure. Followed the trace with magnifyer.
Its a clear and visible trace!

But i cant see this on schematic :S

It should have E14.3 C14.1 B13.1Volts.
And it has!! Not strange that IC703 has ~13 volts on leg 14..

Is it a possebility that there are slightly different versions
of this amp? Because the schematic does not seem to match.

Or is it just me...


Maybe i should just put everything back in place and se how it works. Its frustrating when the schematic does not match the
circuit board...

It's entirely possible that the schematic and the amp you have are different. Many amplifiers have multiple versions.
