Well i don't know how this amp was working before i started the modifications but i pulled the resistor from B- to chassis ground, at an AMPS member suggestion, to measure it, it was open! So i grabb

The handbook is sitting right next to me and I still don't see the math I'm looking for. I need the equation that I can fill in to determine the high voltage when I know the value of the string and t

Ian, Thanks for explaining that further. That formula is what I was looking for.. 2380V x 50k / (10M + 50k) = 11.84V I like to "know" how this stuff works, only way i can learn it for future use! The
