This is the schematic of the power supply for the now infamous 813 Maul by Tom, K1JJ. There is some big iron here, making voltages that will fry you. Remember, these types of power supplies, and the voltages they produce, only kill once!Please ... BE CAREFUL!!!
There are two different high voltage sections shown. One is for a 2.2kV transformer and a bridge rectifier circuit. The other is if you happen to prefer using, or already have, a 4kV center tap transformer and of course a half wave rectifier scheme. You only need one of these. We show two to give you a choice between which ever you prefer. All other components in the HV section remain the same.
