Do you really need it to be variable? I would think +/-15VDC or
+/-12VDC would be sufficient 95% of the time. I bought a power
transformer from Digikey, an IEC power inlet with switch and
fuse, a Bud box, and this +/-15VDC regulator board on Amazon.


If you need it to be adjustable a pair of these might do.


...or these which have built-in LED displays.
