Hi, I was connecting up what turned out to be a damaged mini-jack to phono cable to the AUX input on my Onix amp, resulting in a bang and a bright blue spark.. Now the amp cuts out almost immediately when turned on. When you turn it off the sound briefly comes back then dies again. I guess I've blown something in there. Is it likely to be repairable? Any suggestions of where to get it fixed - I'm in South London. many thanks, Sam.
