ARGH! One channel failed ... where to start?

paulspencer · 23rd July 2007, 01:43 PM

It's an ESP chip amp and one channel has failed. It happened when I stood on some cables, I heard a little zap, the sound cut out from one channel. I've checked cables and they all seem fine. I also can't see how I could have caused any fault.

Now I'm a little stuck. I know how to identify the parts and follow plans, but not how to fix.

Can anyone suggest where to start, what to look for?

Do you have a multimeter? Can you check supply voltage, amp output (DC with no signal) voltages?
