I have a JL Audio 450/4 that has issues with channel 2. I bought the amp with the low ohm light on and no sound on channel 2. I pulled the output fets and checked them with a dmm and they checked out okay. When I powered the amp up without the channel 2 output fets the low ohm light went off and the amp played normal on 1,3 and 4. I also cheched the power fets and c3198 driver. All checked out okay. I measured the rail voltage and got 43 volts. Now, the issue seems to be that I am getting 32.6 volts to pin 3 of q203 and q203 but also 30.2 volts to pin 1 of same transistors. This only occurs on channel 2. Channel 1 gets 32.6 volts to pin 3 but no voltage to pin 1 and it works fine. Any ideas. Thanks.
