Hi Bruce,

I'm the Tom who arranged the TBolt group buy. Along with the
quantity buy of Thunderbolts, after some experimentation and
comparing prices, I chose power supplies from All Electronics
(their model PS-23). They had a large quantity at one time but
we cleaned them out of all stock for that cheap item in order to
bundle a suitable power supply with each Thunderbolt receiver.

So that's why All Electronics no longer has that item. If we had
extras or a solid supplier, then TAPR could sell them individually.
If All Electronics had more of these cheap surplus PS I would
have bought them. I hope that clears up the mystery.

We've shipped some TBolt's already (mostly pre-orders from
last year); TAPR is gathering tested stock now and you'll hear
soon in time-nuts when that door opens.

For some other power supply options see example ideas here:

The +5 and +12 and -12 volt requirements are very standard so
it should be little problem finding something new or used that will
work. Note also there's nothing wrong with using two or even 3
separate supplies (with common ground).
