I went through the amp/receiver and used small star washers on all the grounding screws I could find including the one securing the transformer, cleaned dust off all circuit boards, checked output transistors and fuses, all OK.
Re Assembled unit and it worked OK.
I will buy a fan and fan it to avoid sourcing heatsinks for the previusly suggested IC's.
Thanks for the technical help, sure solved my problem.

More than likly the built in amplifier is dead and its time to lay it to rest. Before you do that, make sure all your positive and negitives are correct and that none of the wires are touching one another.

These models are known for this issue.
I've had my share in the shop here.
Disconnect all speakers,turn speakers off, try headphones only
If it still persists then there is either :
1. power supply capacitors gone bad or 2. The thermal fuse in the transformer is open.
A tech can very easily find out if the thermal fuse is open by checking the primary of the transformer
if the plastic is shrinking away from the power supply capacitors then they've gone bad
