ONE SHOT DELAY B301

This document is a proprietary schematic diagram for a "One Shot Delay B301" circuit, copyrighted in 1964 by Digital Equipment Corporation and intended for test and maintenance purposes. The circuit includes a variety of components such as resistors, capacitors, diodes (D1-D14), transistors (Q1-Q6), and transformers (T1-T3). Key specifications are provided for generic components: resistors are 1/4W, 10%; capacitors are MMFD; transistors are DEC2894-1B; and diodes are D-664, unless otherwise indicated. A "Transistor & Diode Conversion Chart" maps Digital Equipment Corporation (DEC) part numbers to their EIA equivalents. The schematic also indicates power supply connections, including +10V(A), -15V, and ground. The document includes revision history and was drafted by Paul Tellier on June 16, 1964.
