hi all, this is a repost. My last post was in the wrong thread i believe. i finished building a PPAv2 and it sounded great, but overnight it has stopped working. I'm not sure what happened to it, as i live with several other people who use it but when i turned it on I was not getting sound from right channel. Checking the offset yielded a +6V! Q3G+ was getting to hot to touch so thinking maybe this was the issue i replaced it and new offsets are: L-1.5mV, R-1.5mV, G-.44mV. Anyone have any tips on how to find the shorted part. Isolating the rails might help a little and if i'm reading them right (ahem..i've no idea wt_ i'm doing) removing R1 will take a rail out of the loop. Any suggestions/help with troubleshooting are greatly appreciated. I've been spoiled by this amp; my music just isn't the same anymore
EDIT: getting .73V across D1???
