Alright, I got new opto couplers and still no luck. My brother in law came out to visit and has a lot of soldering experience. He cleaned up the board (and all my poor soldering). Not sure if I missed something at this point.

we need to list all the voltages on each pin of the PWM control chip. Its the large one in the center of the opto's. Turn the amp on and let it go into protect and then measure each pin of the PWM chip with your black probe connected to the ground of the 12 volt supply. please list them pin for pin I.E. pin1 = Pin2 = etc...

Another option is for you to directly compare the voltages from your working amps PWM to the non working amps PWM and then just post any differences you may find.

Wow! I put this thing off to the side, pretty much giving up on it. Then I circled back and figured it out. So I initially tested the thermistor by measuring the resistance, heating it up, and making sure that the resistance went up. Well, after tracing everything back over the last couple days and finding nothing, I ended up comparing the resistance of the thermistor on this amp to the resistance of the one on my 50. The 50 was about 50 ohms and mine was about 800. So I put a resistor across the circuit to mimick the 50 ohms and voila! It works perfect!! I am happy as a clam now. I have some sentimental attachment to this amp. It used to drive 2 Lanzar Pro Plus 12's HARD!!! That being said, I royally beat this thing back then since I was running both 4 ohm subs in parallel with the sub wave boost way up and 50hz cranked off my Kenwood 5 band EQ.

Not I need to figure out where to replace this thing. The letters on it are something like PD1 UEISK. That is not bringing up anything for me. Anyone care to help?
