Subject: Re: [time-nuts] Thunderbolt Supply
Hi Larry,
I use a linear supply for mine.
My supply is actually a headphone amp supply kit from JayCar
Electronics
here in Australia. Its basically two LM317's and a 7805 for 5v. I
changed the resistor that set the output voltage from 15v to 12v and
also selected an appropriate toroid transformer to suit.

I dont know if you can get these kits in the US or if JayCar ship
internationally, you'd have to ask.
I'm sure you could find or build something similar state side :)

Tim
There's a 3-output linear power supply kit at
http://www.goldmine-elec-products.com/prodinfo.asp?number=C6895 that appears
to be a good supply for the TBolt. Thinking about ordering one to replace
the switcher that I got with my TBolt (TAPR buy). Price is $33.10 US plus
S/H.
All outputs are adjustable from 1V to full output, but if you want finer
control, you can replace the pots with fixed resistors and a lower value pot
on each output. This kit appears to be complete, with the exception of an
enclosure.
