Regulated power supply

F1 - Fuse 1A/250V
F2 - Fuse 10A/250V
Tr1 - Transformer 12..16V/12A
D1..D4 - Diode 100V/6A
D5 - Diode 100V/1A
C1 - 10'000uF/35V
C2,C3 - 1uF/100V
C4 - 1000uF/25V
R1 - 1.5ohm/5W
R2 - 220ohm/1W
P1 - 5Kohm
T1 - PNP 10A/40V
IC1 - LM317

The output of the power supply can be regulated from 1.25V to about 15V. The maximal output current is 10A. The PNP must have a radiator, for the LM317 it's not necessary because his current stops at 0.5A.
