Power Supply 739A

This document is a technical schematic for the Digital Equipment Corporation Power Supply 739A. It illustrates the circuitry for the power supply, including the transformer input taps, bridge rectification, filtering, and regulation stages. The diagram details the configuration for the "Inhibit Power Supply Control G 800" and the "Read/Write Power Supply G 800," along with specifications for a low voltage detector. It provides component values for resistors, capacitors, and thermistors, specifies transistor types (2N3716), and outlines input voltage jumper configurations ranging from 112.5V to 235V AC.
