[QUOTE="Terrum, post: 8760810, member: 657229"] I sold a Rainbow Dream 1 amplifier about a month ago, it was returned to me as faulty. With no speaker wires attached and gains at their lowest, bass boost off etc, the amplifier goes straight into protection mode as soon as it is powered up, and starts burning the legs off of the fuses. It doesn't actually blow the fuses, it just burns the legs off for some reason. The amp uses the ordinary kind of fuses you would see in fuse boxes of most vehicles. Mind you this amp was serving me just fine for the two years I had it, never over-run. I know I'll probably just have to cut my losses but for my own curiosity I would like to find out what is wrong with it, and if possible figure out if it was damaged during delivery or by user error. As I'm in the UK, finding someone to service the amp is proving difficult so I am potentially looking into diagnosing it myself at least (and possibly repairing it if I can). I'm definitely not an electrician, but I have replaced/resoldered resistors/capacitors before. I also have a multimeter but I wouldn't exactly know where to start on how to find out if there's a short circuit somewhere (to find which component is faulty) or what I should do. Any advice is extremely appreciated and of course any input/discussions on this situation is also appreciated! Many thanks :) [/QUOTE]
