Difference Amp W532

This document is a technical schematic for a Difference Amplifier (W532) manufactured by the Digital Equipment Corporation in 1966. The diagram details the electrical configuration of the circuit, including the arrangement of eight transistors (Q1 through Q8), various resistors, and capacitors. It also provides reference specifications for component tolerances, noting that standard resistors are 1/4W 5% and metal film resistors are 1/8W 1%, while capacitors are rated at 3.9 MFD 10V. Additionally, the document includes a conversion chart for the transistors and diodes used in the assembly.
