Power Supply

Quantity	Description					Schematic Part Number

1	AC cord with ground wire and plug			Power Cord
1	4 amp fuse with fuse holder				Main Fuse
1	Neon indicator lamp                                     L1
1	Stancor P - 8663 24 VDC CT transformer                  T1
1	4 Amp bridge rectifier                                  BR1
1	5,000 mfd Capacitor or multiple 2000 mfd                C* (filter capacitor/s)
	* Electrolytic type  to achieve mfd
1	5 pin DIN connector socket
1 	5 pin DIN cable
1	Utility Box (or build on suitable platform, Formica perhaps)

A ready built supply can be used,  either  24 VAC or 18 VDC. If you use a 24 VAC supply, 
you will need to build the bridge rectifier and capacitor portions of the power supply 
circuit to obtain the 18 VDC required by the system.
