Power Supply DC variable
Capacitor C1 can be 2200 to 6800?F, 35 to 50V. For Q4 charge be army on heatsinks to accumulate a acceptable breeze of acceptable output. For the 2N3055 transistor (Q4) can be replaced with a hardly beneath able TIP3055 type.
Componen used:
P1 = 500R Linear Potentiometer
P2 = 10K Log. Potentiometer
R1, R2 = 2K2 1/2W
R3 = 330R 1/4W
R4 = 150R 1/4W
R5 = 1R 5W
C1 = 3300?F 35V
C2 = 1?F 63V
D1, D2 = 1N5402 3A
D3 = 5mm. Red LED
Q1 = BC182
Q2 = BD139
Q3 = BC212
Q4 = 2N3055
T1 = 220V Primary, 36V Center-tapped Secondary
