Mcintosh mc440m in protect mode


2010-09-30 4:18 am
i purchased this amp used off ebay. when i originally powered it up,the amp did nothing. i proceded to take it apart. i found a overheated wire[ BROKEN] in the circuit board coming from the sub sw. and going to an input amp. made the repair, repowered the amp and the fans turned on but so did the protect led. when the amp is in 4 5 or 6 ch with sub sw. to out, the amp stays in protect. when in 6 ch with sub sw to 120 or 80, protect led goes off. i have replaced all leaking caps but still the same.i was hoping someone from here might be able to point me in the right direction. thanks in advance, shawn:confused:
