• Notes
• This is a hybrid tube/transistor power supply rack-mounted using a special five-module rack adapter. It is interesting in that the transistors, 8 top-hat silicon rectifiers and two heat-sinked stud-mount silicon rectifiers handle the high voltage/power responsibilities while the tubes are used in the regulation control circuitry.
