[Winky Dink]

Thanks, guys. I wasn't finding any shorts. Following Old Coot's post I started checking voltages at the plus side of all the electrolytics. Some of the readings didn't make sense--AC instead of DC, meter unable to settle on any reading. The diode polarities were right, but I had the negative side of M2 connected to the C1 negative (which, as I previously learned, does not go to ground).

I straightened out the wiring, and as soon as I turned on the power I could hear the flyback. I checked just one voltage: V18 now has the appropriate 380volts versus the previous 200volts.

Thanks a million. I'll pick up on this later tonight.
