Part list for 12 Amp BDX33-based power supply:

2 x 15 volt 6+ amps

2 times two MR750 (MR7510) diodes (MR750 = 6 Ampere diode) or 2 times 3 1N5401 (1N5408) diodes.

F1 = 1 Amp

F2 = 15 amp

R1 2k2 1 Watt

R2 10k

R3 1k 0.5 watt

R4,R5,R6,R7 0.1 ohm 10 watt

R8 4.7

R9 6k8

C1 two times 4700uF/35v

C2 330uF/35v

C0',C3,C4,C6,C10 100nF

C7 330uF/25v

C8 47nF

C9 47uF/25v

D1 1N5401

D2 LED

D3, D4, D5 1N4001

IC1 78L15

relay 12 volt 2x5 amp switching

3 darlington transistors: T0,T1,T2 = BDX-33 NPN TO-220 transistor

Zd 8 or 9 volt, 5 watt

P1 2k trimmer

If using a bridge rectifier (like in schematic 2) you do not need 2 x 15 volts 6 amps, but 1 x 15 volt 10+ Amps
