Need advice on repairing a Marantz PM94

I think I might have damaged the stage that checks the oveloading of the amp by trying it with my Infinity 9.2 which have very low impedance. Now the PM94 is hooked to normal 4 Ohm speakers and when the amp is cold it has a tendency to cut off on the left channel.

It starts with a few scratches and then a click and both channels are out. Later everything comes back (If volume is turned down) and then everything is fine for that listening session !

I am no technician, but I know how to solder, is there any way to fix this without making big expenses, specially that everything else works perfectly ?

Many thanks for any suggestions
