I bought an ad30vt from ebay a couple of weeks back and there seems to be some problems. When I'm playing the volume drops and only comes back if I tap the amp on the side and even then it will jsut drop again after a little while.

The seller gave me the dispatch note which shows it was only bought at the beginning of june, so should still be under warranty.

it was bought from www.soundslive.co.uk will there be any problems in replacing it because im not the original buyer or will i be ok?
