Banda Viking 7000

Was hoping you can help me out with a problem I can't seem to figure out.
I have a Banda Viking 7000. All mosfets are good, all signals and rail voltages
are good. Unit will power up, draws 3.1 amps and plays.....But, here's the problem,
there are 6 resistors in parallel (R74 thru R79 all 22k ohm smd) that are located right
behind one of the large 1000ufd 200v caps, after about 30 seconds these 6 resistors
start to get very hot and will eventually burn open. Any help identifing this problem
or what curcuit those resistors support would be very much appreciated.
thank you
