If it's under warranty, for gods sake send it back - ignore the helpful suggestions that it might be dirty mains power, dodgy mains lead etc. as even if that is the case, a well designed amplifier should cope with these things. There's a good reason why these have a very bad reputation - whilst you still have the chance to get it sort free of charge do it.
It's only my opinion, but these amps seem to fundamentally flawed in their design - when I returned mine the shop said 'Another one for the pile' - apparently they weren't bothering to return them for repair as the returns rate was so high, just offering credits against something else.[/quote]
I agree totally, at end of the day in some cases, things have got just too cheap to be reliable, The Little Git (Giant) even though it seems to be more reliable than the Superfly has some major design flaws . Both Amps are great if you get lucky and get a good one, but why should you put up with the stress?. I don't have a high opinion of the Blue Meanie these days, my early UK made ABM was great, never had any problems, but I have heard of many issues with the new ones, great design just assembled poorly. Always an issue with having stuff made in China, having good inspection of your stuff, with someone you trust is the most important thing. Having a container load of stuff delivered, which you have already paid for, the temptation to let it go out is all to great. I see they making the valve series valve / ss in the UK, so hopefully this will be ok. If they started making ABM's in the UK I would be first in the cue!
I am just off to try a new AH600-12, same price as an ABM (albeit a different sound) USA made, 5 year no quibble warranty can't be bad
