Got another one of theese in with the same problem..
Amp stsys in protection mode ..
If i remove all of the outputs from the right channel amp will power up and produce clean audio from the left channel..
I replaced every transistor in the right channel put new outputs in it and amp will be stuck in protection mode..
If i remoe all outputs from right channel it will power up
Any ideas??

There may be multiple problems. With that much DC, the differential amp should be driving the amp to draw current as it tries to eliminate the DC. Since it is not, either the differential amp circuit is damaged, there is a shorted driver or both. There are other possibilities but those are the most likely.
I found that the Drivers (TIP31C and TIP32C) for the outputs have 53 volts on all 3 legs ..
I started removing 1 transistor at a time to get rid of the 51 volts on the legs of the drivers..
i think a few are defective..
anyone know if there are any good subs for theese??
C2229
A970
I have some C2235's on hand wondering would thoose be a good sub for the C2229 or not?
