Power Supply 779A

This document is an electrical schematic for the Power Supply 779A, produced by Digital Equipment Corporation in 1963. It outlines the circuitry for two transformer-based power regulation sections (utilizing DEC 1021 transformers) with associated capacitor banks and diode bridges. The schematic includes a table detailing jumper configurations for various input voltages, ranging from 112.5V to 235V, and provides technical specifications regarding component types (e.g., Heyman Mfg Co tabs and Cinch Jones terminal strips).
