Default Lighting audio S2.300

Got this amp in for repair. The guy said he blew 2 subs off this amp.I checked it out and found 2 shorted outputs. I replaced the shorted outputs and moved all pots/switches around several times. But the channel that was blown still has an issue with new outputs in it the channel distorts like crazy.
I checked all op-amps and have + - 15 volts on them all other pins 0 volts.

It looks like they are using the 5 watt ceramic resistors for the emitters

Wondering what else i should check since the left channel distort's like crazy

I figured it out. It was some bad solder connections
