|[AMRadio] Voltage regulator|

This last week I built a 12 volt and 24 volt power supply in one small box
to power various relays around the shack.
Well, the 12 volt turned out to be 16 volts, and the 24 volt is 36 volts.
Even loaded the voltage is high.
I've done quite a bit of Googling on the subject of three-terminal voltage
regulators, but have found nothing that had actual component values that
would be pertinent to my needs.
Also saw a three-terminal using a pass-transistor. Again, no actual
I'd like to be able to get the voltages down to more nearly what I need so
that I don't burn out a relay. Perhaps 14 volts and 26 to 28 volts, at an
amp or so.
My knowledge of solid-state devices is close to zero.
Anyone have some ideas?
