There is a current limit for the VCC rail. Duty max is doing this. So I don't believe the high current was flowing from VCC via IC503 to GND. Maybe something is wrong around the BS170
Good catch, Ludwig. I guess I was writing when you posted. You are always more careful than I am in diagnosing things.
Han, you should order some BS170, too, if you don't already have some, and Ludwig is spot-on in recommending you look around the BS170s for additional issues.
