Some regulated supplies have 'sense' terminals which, when connected together,
assure that
the output voltages will track. I had two Astron RS-70 12 volt supplies that I
used to
power a solid-state amp. that had terminals for this.
Without such a connection, it MIGHT be possible with similar supplies if you
adjust the
output voltages to be as close as possible and strap the supplies in parallel.
I haven't
tried this!
Someone can probably tell you where in the regulator circuitry to go to add a
sense
connection for supplies that don't have this feature.
