Re: Need help with broken amp!!!!!
well if it was stored in damp environment there could be corrosion on the internal parts which could short or give cold solder joints. Also capacitors do have a self life and are sort of like batteries in that they need to be used and can go bad after setting inactive for so long.
crack open the amp and look for obvious issues like burn marks from damaged parts, or rust/build up, look for loose connections and anything out of the ordinary.
be extremely careful some capacitors can and do store large amounts of electricity at more than enough amperage to kill/seriously injure you. As long as your just looking and not poking around you will be fine.
if you dont see anything wrong you'll have to find and invest in a good amp tech. Then just go from there.
