Found a couple of things...

The cap resistor combos used on the amp - the blue large body resistors - the color code of 20 ohm (Red - Black - Black), but schematically they use 39 ohm (Orange - White - Black)...

So already some works been done to it, but the resistors are not the issue, the caps in line with them are...

[ATTACH=full]30959[/ATTACH]

They look like AXIAL types, not radial. So to see that kind of work scares me - they are located as part of a feedback loop to keep the amp clean - there is a lot of power that pumps into this circuit (all four of those pills use this pairing) - and if the caps or resistors are not up to par or can't handle the rated power - they'll blow and well - as you can see by the RED ARROW - you have a blown resistor as Audio Shockwave has revealed.

So my research concurs with his - yes the repair is a bit or work to be done to get it back right...
