This listing is for one used Giddings and Lewis Servo Interface circuit board, assembly number 501-03882-00, schematic number 502-03092-00, manufactured by Giddings and Lewis Electronics. The board carries serial number A16869 as visible on the barcode label at the board edge, with a revision date code of RC 5/84 silkscreened on the top side. The PCB is configured as a single-axis servo interface card with dual power transistor assemblies (National Semiconductor LH0101CK) mounted on heatsink brackets, precision Dale RS-7 resistors rated at 100 ohms 0.05%, and multiple LM301 and MB444 op-amp ICs. Silkscreen designations include GAIN, BAL, COS, RES, CMD, DRV, SIN, IND, FDBK, and GND signal points along the left edge connector, with SERVO CHAN and P1 CONN edge connectors at the bottom and right sides. Signal conditioning components and layout are consistent with analog resolver feedback servo axis control used in Giddings and Lewis CNC machine tool systems. All components appear visually present with no visible signs of burning, cracking, or physical damage. This board is intended for replacement or spare use in compatible Giddings and Lewis CNC systems utilizing this servo interface assembly. Buyers are responsible for confirming compatibility with their specific machine configuration prior to purchase.
