PRINCIPLES OF OPERATION
REV.-A
2.2.8 ± 12 VDC SUPPLY CIRCUIT
The voltage from the transformer is rectified by D22 or D23, and + 12 VDC is produced. Theory suggests
that load variations can cause large variations in the output voltage. In particular, output voltage may be
quite high under no-load conditions. To prevent this problem, dummy resistors R24 and R25 are inserted
into the circuit.
