i took to it a guy i know who fixes amps today just to see if he could see any problems and he said there no dry connections. so he took the speaker out had a gander behind and we found a small bagpuss, a ty beanie toy, a stuffed rabbit and a plastic pirate figurine. so we took them out put everything back in place and bingo it worked.
what are the odds?
actually a pretty nice amp im chuffed for a freebee
thanks everyone that helped
