  • Where did you get the pre-assembled boards? I have an old PA system, the pre-amp circuit board works fine but the power amp is toast. It runs on the LM3886T Op Amp. I replaced the op amp because I could visually see that it had a crack and was smoking, but now it fries speakers. I would rather replace it if I could.

  • Well, if the IC keeps on smoking, may be you’d want to check the power supply section first 😉
