Tu-10 Capstan Servo Preamplifier G932

This document is a technical schematic diagram for the TU-10 Capstan Servo Preamplifier (G932), produced by the Digital Equipment Corporation. The circuit layout illustrates the arrangement of various electronic components, including transistors, diodes, resistors, and capacitors, used to manage capstan servo functions. Key features of the schematic include power input rails (ranging from +14V to -14V), connections for rewind and reverse speed control, and an operational amplifier stage that produces the final "AP output." The document also includes a transistor and diode conversion chart to assist with maintenance and component identification.
