This is circuit power supply regulator variable voltage 0-30V at 1A.
it is old circuit I used IC ua741 or LM741 OP-AMP IC for control adjustable Votage by VR1 (see in image circuit).
The transister 2N3055 is classic part for booster current up to 1Amin.
I used transformer 2A. it big size in PCB but sure current peak 1A min.
