>>"the meter reads 7.9 volts If this is the metering internal to the KPA500:
Maybe the transformer taps are wrong or bad? If we had a schematic of the power supply we could find a location to measure the HVDC with an external meter. (This would be like working on the plate supply of an old vacuum tube amp, not like working on a 12V powered QRP rig -- be very careful! ) Maybe it is really 79 volts, but the display has a stuck decimal point? Does that decimal point stay _all_ the time? Even when the display is used for other readings/messages?
