Description
Offered here is a Heathkit PS-4 variable high voltage power supply. This is one of many "lockdown" restoration projects I took on this past year. I'm probably taking a loss on it but it was the fun of doing the work that was worthwhile for me. I've done several of these supplies and only need one. This unit is in good condition with scuffs and scratches from normal use.NOTE TO BUYER:
The tubes have been removed from their sockets and the top cabinet handle has been removed. These items are packed inside the cabinet for shipping. The buyer will need to open the cabinet and reinstall those in order to use the unit.
Basic Specs:
HV output 0 to 400VDC at 0 to 100mA continuous, 125mA intermittent.
Bias Output 0 to -100VDC at 1mA
Filament Output 6.3VAC at 4A.
