Delay R302

This document is a technical schematic for the "Delay R302" module, produced by the Digital Equipment Corporation in 1964. The diagram outlines the electrical circuit design, which utilizes a variety of transistors (DEC3639 and DEC3009B), diodes (D662 and D664), resistors, and capacitors. It specifies standard component values, noting that unless otherwise indicated, resistors are 1/4W with 5% tolerance, capacitors are measured in MMFD, and the primary diode type is D664. The document also includes a transistor and diode conversion chart and references the associated parts list, A-PL-R302-0-0.
