    Enclosed are pictures of two power supplies I picked up last year.
    One is an Excelon Power Systems, Part Number 1565, manufactured in 1977, the other has no mfg. information. The guy who threw them away also threw away some camera and microphone items with an old logo of a Dallas area TV station.

    I've tested them with my limited capabilities, and they seem to work.

    I'm curious about their intended use, and whether they have any present day usefullness.

    Thanks, Gary

    They are good for parts for when you build your own power supply. Much safer simpler to use a transformer (and those look hefty!) than to try an off-line swticher.

    Other possible uses: Doorstop, boat anchor...:)
