Pulse Amplifier S603

This document is a technical schematic for the Digital Equipment Corporation Pulse Amplifier S603, dated 1965. The diagram details the electronic circuitry of the pulse amplifier, illustrating the arrangement of resistors, capacitors, transistors (DEC 2894-2B and DEC 3639-C), and diodes (D-662/D-664). It includes specific component values, connection points (labeled J through U, E through R), and power rails (+10V and -15V). The document also contains a parts list reference and a transistor/diode conversion chart for maintenance and testing purposes.
