I think I just bust my reciever. It was a Sherwood 925 RDS. I put some music on, turned it up to about half way and all of a sudden the was quite a big bang and then white noise from the speakers. I turned everything off and then waited and turned it back on. Now the Front channel doesn't work. The speakers are fine though. It also appears to have absolutley mangled a whitenoise mos125 power amp as well, and that was home built and not guaranteed. Are there any lessons to be learnt from this? (Don't build your own power amps?)... The power amp was on a line out and the reciever front channel amp doesn't work either. I can take it to the shop I think and get a refund, but I was just wondering if I had done something stupid and theres some way of reseting something?
