So I checked DC voltage at Pin 8 on the Rectifier. I am expecting about 379V DC as the rectifier has a 1.13 conversion and I am using 330V or 660V center tapped. However I seem to be getting more like 319V DC? Any suggestions as to perhaps why? In addition, now when i discharge my cap’s there is no voltage present? I notice the mounting bolt for the board is very very near the negative terminal for the capacitor right above it. However this line is grounded as well, so could the contact between the bolt be causing a short? I was thinking no since it was grounded already but is this sound?
