W702

This document is a schematic diagram for a Teletype Level Converter, model W702 (part number W702-0-1), designed by Equipment Corporation of Maynard, Massachusetts.

The circuit primarily features:

• Numerous resistors (R1 through R26) with specified values (e.g., 1,000, 1,200, 1,500 ohms), rated at 1/4W with 5% tolerance unless otherwise indicated.
• Multiple diodes (D1 through D14), which are type D364 unless specified.
• A single capacitor (C1, 0.01 MFDI).
• Various input/output points labeled D through P, and R through V.
• Power connections for C GND (Ground), -OB -15V, and -3V STRATE.

The document also includes a partially empty "Transistor & Diode Conversion Chart."
