I am trying to powr an old test instrument with a dead supply.
What would be the most straightforward way to make a regulated DC power supply with the following four voltages plus earth reference?
+12V +6V0V (Earth reference)
-6V
-12V
250mA per rail, eg. 1A totalOne possible option might be to use a 1A 12VDC regulated plugpack, and build from there. I assume that would eliminate the need to regulate the remaining three voltage outputs separately.
Thanks for any suggestions.
