Damaged are you a hi-fi repair man? I ask because I bought a brand new Technics stereo system a couple of years ago and its always had a problem where if you have the volume over a certain amount the amp cuts out, the volume just knocks off but the amp is still turned on. I should have sent it back to where I bought it from but "I couldnt be arsed" Ive been wanting to get it fixed for ages but there is no where around where I live (Chorley). Is this something you could sort out do you think? Its a Technics SC-HD550. Cheers mate.
