Regulated Power Supply 605

The Kepco 605 is a heavy-duty high voltage regulated power supply that weighs over 80 US pounds.  It uses three parallel 6336A dual triode pass tubes fed by three parallel 5R4GY rectifier tubes. To ease the requirement of regulating up to half an amp at the lower voltage points with a top end of 600 volts DC, the main transformer supplying the regulated B+ is controlled by a variac. The variac shaft has an insulated coupling to a flexible shaft that turns a potentiometer voltage control enabling a single control for regulated voltage from zero to 600 at up to 500 mA. Two voltage regulator tubes are used,  a 5651 (87 volts) and an 0A2 (150 volts). A 25K ohm potentiometer provides a variable C- bias supply from zero to -150 volts. The voltmeter can be switched to show 150 or 600 volts. The current meter goes to 500 mA full scale. The 6.3 VAC filament supply can source up to 20 amps. Shipping weight is listed in catalog B-611 as 119 pounds. Kepco price list in catalog B-611 shows March 1961 but the supply is likely older than that.
