K4HV GS35b Amplifier High Voltage Power Supply


Here are some pictures of my HV power supply used for my 6m and 2m amplifier decks. It includes step-start and EMI filtering. A Peter Dahl transformer rated for 240VAC/2700VAC 1.5A CCS makes up the bulk of the weight. 14kV K2AW rectifiers provide the rectification. A small box fan mounted to the lid (not shown) provides air circulation over the bleeder resistor stack. A large 50 ohm resistor is used to limit current surges in case of a tube arc.
