H board/HV board

These H boards are relatively reliable. Here Barco combined the H output and the HV section. There is a thick red lead that goes to the HV quadrupler. If you’re taking this board out, let the chassis sit for 5 minutes before you loosen this HV lead to discharge any residual high voltage. Touching a metal screwdriver to the screw before it’s fully discharged can zap you!
