<>There are only three voltages on the bus, +8VDC, +12VDC, and -12VDC, whic
<>in reality are usually closer to +10~12VDC, +16~18VDC, and -14~18VDC.

A good way to soft start a old powersupply that is also short safe is a
100-200W 110v (or equivalent for other countries) in SERIES with the
110v power. If the supply is shorted you will get a bright light,
if it's ok it will Dim gradually or quickly to a dull glow or less.
Works well for forming caps that arent totally gone.

It's cheap and easy to make.

Whille the lamp is in series with the source you can check the unloaded
powersupply voltages, if the look good you can use an auto 12V bulb for a
1A load or a headlight for a 5-8a load.
