Many low cost triple output power supplies are designed to power digital
circuits (e.g. +5V) with maybe some RS-232 or analog circuitry (+-
12V). Since the only 'important' voltage is +5, that's the only
voltage that's regulated. The others are designed to be within maybe 5%
up to the rated load. I see various power supplies on fleabay that are
sold for use with the Thunderbolt that seem to fit this model.
In the Thunderbolt the +12 runs the oscillator. Won't an unregulated,
but relatively steady, +12 supply degrade the performance of the
oscillator or does the Tbolt have a built-in regulator to deal with this?
