GE Superbase has had this very loud crackling in the receive. I cannot tell where it is coming from. I replaced all of the elec. caps on the top board (which is 99% if not all of the RX and audio). I will be replacing the audio IC in this radio anyway. And i can't quit get the RX to open up anymore than it is. It's not as good as I think it can be. I installed the 2sc2999c in for the RF amp, but that actualy did worse. Is there a better gain amp than a c763 (stock amp)?
Back to the popping and crackle. It happens in both CB, CB/PA, but not straight PA. But that makes since that it's not in the mic or mic amps. I've also used different mics as well. The original tested just find on mic tester as well. Would the main power cap 4700uf be causing this issue even if it's ONLY in cb and cb/pa modes? I doubt it but thought i could ask anyway.
