Calibrated Timer Control K376

This document is a technical schematic from 1967 for a "Calibrated Timer Control," produced by the Digital Equipment Corporation. The circuit consists of three main components connected between a top screw and a bottom spacer:

• R1: A 250,000-ohm, 10% tolerance variable resistor (Allen-Bradley TSRA254I, modified clockwise log taper).
• C1: A 2.2 microfarad, 6V capacitor (Sprague 150D226X9006A2 or equivalent).
• R2: A 4,700-ohm, 1/4W, 5% tolerance resistor.
