Looking for suggestions on supplying the DC power to a
TU-56.....
You need +5V at 0.8A and -15V at 0.8A, both regulated to +/- 10%.
(You can optionally use +10V at 0.8A instead of +5V, with suitable
wiring.)
It should be easy to find a surplus triple-output power supply with
+5 and +/-15V, and simply not use the -15V output. New, these cost
around $70-80.
It may be easier and/or less expensive to use separate 5V and 10V power
supplies. For instance, Digikey has wall-wart style switchers that are
suitable:
T920-P5P 5.0V 2.4A $14.03 each
T924-P5P 15.0V 1.0A $14.03 each
Since they are isolated (as all common AC-to-DC power supplies are),
you can use them as positive or negative supplies.
