Hi am looking for help with this RF Prime R600x5. I have power and no sound. I have rail voltage -41.34 and +41.47. I have a 37.5 kHz signal on power supply FETs. Not sure if I just have a muting problem or what.
The only board that plugs in is the RCA board. The other 2 boards are soldered in. The power supply (pwm) board has a LM358 I don't see a LM339, and there is only one.
