4 Ampere Regulated Power Supply 0 18V circuit

This circuit is power supply with voltage and current regulatable, with maximum current 4 Ampere for voltage range 0-18 Volt. Final power is composed by two of 2N3055.
 
P1 sets maximum current of power supply, if do not need or want to be able to decrease amperage, then you can remove P1 and connect P2 to the 680 Ohm resistor. P2 regulates output voltage between 0 and 18 Volt DC. P1 trims to calibrate M1 voltage meter. RFC1 and RFC2 are 50 turns 1 mm AWG on ferrite diameter 0.8 mm. The two Final transistor 2N3055 of the power supply need large heatsink for cooling.
