base of 3A1Q1 is biased by the reference amplifier

via inverting-amplifier 3A1Q2. Transistor 3A1Q3

The electronically regulated power supply in-

and its associated circuitry provide a constant

eludes a 115/230 volt ac, 55 to 65 Hz dual

current of 1 milliampere (ma) to the reference

primary, power transformer (3A1T1). Its

amplifier and output stages. The regulated

secondary, in conjunction with rectifiers (3A1CR1

output voltage appears at the collector of 3A1Q1

An adjustable voltage divider across the output,

and 3A1CR2), is weed in a full-wave rectifying

circuit. The rectifier output is applied to the

consisting of 3A1R12, 3A1R13, and 3A1R14,

emitter of series regulator transistor 3A1Q1. The

permits adjustment of the output voltage.
