Filtered Differential Amplifier G590

Summary This document is a technical schematic for a Filtered Differential Amplifier (G590) designed by the Digital Equipment Corporation in 1969. The diagram details the circuit configuration, including the arrangement of transistors (such as the SDA-5, 2N4250, and DEC6534D), resistors, capacitors, and diodes required for the amplifier's operation. It also includes notes on component specifications (e.g., standard capacitor voltage, resistor wattage, and transistor types) and provides a conversion chart for various transistors and diodes used within the assembly.
