Default Yamaha R-9 need schematic


Hi;

I just replaced outputs, drivers, .22 ohm resistors etc, in this R-9.

There's still a problem with that channel (DC through spkrs) and
protect relay won't fire until I disconnect the one of the collectors
of either the output transistors. Or drivers.

I have checked all the upper stage transistors, resistors, diodes
and caps in the area that I can find. Something's still amiss.

Does anyone have a schematic of this amp ?

Any help appreciated,

Rick
