I need a little help here, I can solder and replace components as necessary, but not a lot about troubleshooting. I have a mint pair of BP2006, one of them was recently unplugged to move. When it was plugged back in, there was a loud pop and the amp blew. I got a replacement from ebay, when I pluged it in, it popped, but worked fine. I had to unplug the RCA cable to push it back in place, when I plugged it back in, the new amp blew!! They worked fine for the past year, now I am afraid to do anything with them? Any ideas why it would suddenly be this sensitive? The other one is fine, but now I am afraid to unplug it too!
