[time-nuts] Thunderbolt Power Supply Question

[Ed Palmer]

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?
