Well I've finished building my Amp6 B but it doesn't work. When I plug it in with a 12V adapter positive polarity the Tripath chip gets really hot even without the jumpers on. When I reverse the polarity of the adapter I get about a 12V reading at the power terminals on J3.
After that I can't get any measurements. Just 0's.
I thought that 1D might be on backwards but it looks the same as in photos posted. It may well be that some of my joints are not soldered well enough. Please have a look at the front and back photos and tell me what i've done wrong.
