General Purpose Power Supply

General purpose power supply schematics:

You can select the output voltage range by 0-30V or 0-40V of 0-60V. The components value will be different depends the output range you choose.

Vout	Iout	R1	R4, R5	R9	Tr1	C1/C5	IC1	Tr2	Tr3
0-30V	1.3A	0.47Ohm	33k	2k7	24V/2A	40V	723	BD242	2N3035
0-40V	0.8A	0.82Ohm	47k	5k6	33V/1.5A	63V	L146	BD242A	2N3035
0-60V	0.6A	1.2Ohm	68k	19k	48V/1A	80V	L146	BD242B	2N3442

Please check the output current since higher voltage output will decrease the current output.
