Hi there,

I have an old completed K4020 MOSFET Amplifier kit here which I built years ago. It was working well for a couple of years and then suddenly started blowing speakers. I never managed to diagnose the problem and don't even recall if it was in one or both channels. So this is quite a debugging project for someone. I was never very well trained in electronics and only just managed to build the thing so I'm afraid fixing it is beyond me.

Owing to the weight of the amplifier I am reluctant to post it anywhere, so this may only interest those able to collect it from me in person in Hackney, East London. I'm not far from Old St tube.

Open to offers.

Cheers,

Eliot Stock.
