Best Adjustable 20V Supply Circuit Diagram

Build a Best Adjustable 20V Supply Circuit Diagram. This Best Adjustable 20V Supply Circuit Diagram, can deliver 3 A or more and a maximum dc voltage ol` a little over 20 V. It is designed around the readily available LM317T adjustable 3-terminal regulator and has a pnp power transistor to boost the current output. 

The transformer has an 18-V secondary rated at, 6 A; this feeds to bridge rectifier and two 4700- capacitors to yield around 25 Vdc. This voltage is fed to the emitter of the MJ2955 transistor and to the input of the LM317 via a 33-Ohm resistor.
