MARANTZ PM66-SE blowing a fuse, please help

[gregb]

My Marantz amp had an issue on right side ( feeble noise sometimes, that would come back if I unplugged the jack and replugged it or the speaker connectors).

Speakers work great on my arcam so I thought it's the amp, dry joints...

I reddid the solderings, though some solderings went wrong, had to redo the traces with strip wires.

It worked fine for 30 minutes (I mean really fine, better sound, very warm and rich that I ever heard it since I bought it second hand a while ago)...

Then it blows fuses.

Where to start checking?


Thanks in advance

Here's a schematic link. Most common amp failure is output transistors. Also, recheck your solder work.
