OK. So here is the latest.
My packet of MPS8099 and 8599 transistors arrived about a week ago. I bought heaps because I don't want to have to go through that again. Timing was rubbish , because I haven't had an opportunity to put it all back together until today.
Everything went back in ok and when I switched it on there were no pyrotechnics.
I then played through it and the same channel was dead. All the fuses were intact but I was getting no output. I tried alternating the cables to eliminate dodgy cables and that was when I noticed that there was in fact some signal in that channel, just very very quiet. I had to have the volume on that channel all the way up and I could only just hear it. The other channel that didn't blow is behaving completely normally.
So, not all bad news, the sound was fine, just very weak. Any ideas of where to look next?
I hope everyone had a nice Christmas.
Cheers,
Mike.
