Before turning on power the resistance checks were all good. Everything looked good, didn't see any problems. The first 2 tests went without a hitch, so perhaps I was a bit cocky.
I turned on the power to do alignment and test part 3, got a loud snap, bit of phenolic smell.... Not exactly what I would have liked to happen:-( Q7 was toast. I thought that perhaps I didn't get the insulator on the screw properly as it's a bit tricky. I also found I had inadvertently forgot to install Z1. So I put it in, and I replaced Q7 with one from the second K2 kit, but no joy. I basically now have a 12V short to ground: Q7 collector 24.5 Ohms Q6 base 118 Ohms- right where it was before Q7 base 2 Ohms U 10, 11, 12 are all as before. Anyone have any thoughts before I just start pulling the surrounding parts? John K2QY OH NO!
