Dual Voltage Regulator

This document is a technical schematic for a Dual Voltage Regulator (A708) produced by Digital Equipment Corporation in 1970. The circuit diagram illustrates the electrical connections for providing two output voltage rails: a negative rail (-15V) controlled by transistors Q3, Q4, and Q5, and a positive rail (+5V) regulated by transistors Q1 and Q2. The schematic includes component specifications, such as resistors, capacitors, and diodes, as well as a transistor and diode conversion chart.
