Blast City Mono Audio Amp Problem

Post by capcomguru »

Hey everyone-

Does anybody know why the mono section of my Blast City audio amplifier dies so easily? I had the original amp die about 6 months ago, I figured it was due to old age. I swapped it out with an identical model 3 replacement and all was good. Last week, out of no where, the mono audio was gone, AGAIN! You can barely hear the mono audio if you crank the volume up, however its extremely noisy. The Stereo audio portion works with no issues...

I have ordered a third replacement to get it going again, but it begs the question... what the heck is going wrong? Do some PCB's send feedback to the amp and that blows it up? Did I have the volume too high on my PCB's, and that blew it up? Are they just really junky and die all the time? Is there a way to protect the amp so this doesn't happen again?

Thanks for any pointers!

before you swap it out again, reconnect the RA connectors on your cab io. not sure why , I've had that happen 2x on a blast. lost mono only until i reaseated the connector.
