We have a small community center where locals get together and jam once a month, some are pretty darn good. The audio system includes a Pyle Pro PTA1400 power amp. Channel A has been problematic for a while, turn it on, no sound, turn the volume way up, there is a deafening bang, then it would work normally. It has now died on channel A, channel B continues to work fine. Did the usual cable swap, no joy, it’s the amp. Opened it up, wiggled connectors, tapped on things, flexed boards a bit, not a peep. We are in a rural area, services are a hour or two away so I took on the project of trying to get it fixed. First, does anyone have a schematic they could share? I contacted Pyle, so far no response. Any suggestions as to what to look for - problem seemed like something was breaking down with the volume up high?
