MFOS Bi-polar Power supply

This is a excellent PSU

i'VE built an earlier one & it works well.

It uses LM78XX/LM79XX or LM78LXX/LM79LXX regulators
That is, it uses an AC output wall wart.
 DO NOT USE A DC OUTPUT WALL WART.

These are the parts needed:

1	LM7812 +12V Voltage Regulator	LM7812	U1
1	LM7912 Voltage Regulator	LM7912	U2
2	Resistor 1/4 Watt 5%	2.4K	R1, R2
6	1N4004 General Purpose Rectifier	1N4004	CR1, CR2, CR3, CR6, CR4, CR5
6	Capacitor Electrolytic	3300uF	C1, C2, C3, C6, C7, C8
4	Tantalum Electro (35V)	1uF	C4, C5, C9, C10
1	9 to 12 VAC Output Wall Wart	12VAC Output
1	Optional SPST Switch	SPST

Tantalum capacitors -- they are polarized.
