[ARC5] Power supply

[Glen Zook]

Back in high school, I was a member of Army MARS.  Every couple of months MARS members would receive a box with 101-pounds of "goodies", usually miscellaneous parts and assemblies.  However, in either 1960 or 1961, as part of the 101-pounds, I received a "universal"power supply (brand new).  This power supply was about a cubic foot in volume, maybe a little larger (if I remember correctly), was in a waterproof case, and put out all the voltages to run ARC-5 or similar equipment.  The supply was pretty heavy.

This power supply had provisions to operate from 6-volts DC, 12-volts DC, 24-volts DC, 110-volts AC, and 220-volts AC.  All that had to be done was to apply the input power to the proper pins on the input connector.  Also, inside the supply was a small cylinder that contained the schematic of the power supply, printed on silk, that was about 2-feet by 3-feet in size.

I went off to college, and then got married my junior year and, after that, only returned to northwestern Indiana for short periods of time.   When I "left home" the power supply was in the basement of my parent's house.  I don't have any idea as to what my father did with the supply at a later date.  It just wasn't "there" when I came to visit one day.

Anyway, I wonder if anyone, based on this very brief description, has any idea as to just what this power supply was.
