Tapped Delay Line B311

This document provides a technical schematic for the B311 Tapped Delay Line, manufactured by Digital Equipment Corporation in 1966. The schematic details the electronic circuit design, including the arrangement of transistors, diodes, resistors, and capacitors. It specifies that the delay line (DEI) is a DEC 16-05529 delay line with 25ns taps. The document also includes a conversion chart for transistor and diode types used in the circuitry, along with assembly and revision information.
