There are several different power supplies with schematics.

I posted a question several days ago about needing a design for a simple
DC power supply of about 2amps at 12v that is adjustable from an
external pot. I got several answers, but none that gave me a design for
a supply. The supply does not need elaberate regulation or filtering.
Anybody got a design?

Thanks -
