Delay Line W301

This document is a technical schematic for the "Delay Line W301," published by Digital Equipment Corporation in 1967. The schematic illustrates the electrical circuitry, including a series of delay line components (DE1 through DE4), various transistors (DEC3639B), resistors, diodes, and capacitors used in the module. It provides specific component values and power requirements (labeled for +10V, -15V, and ground connections) for testing and maintenance purposes. The document also includes a transistor and diode conversion chart and references the associated parts list, A-PL-W301-0-0.
