This is a used Giddings & Lewis Electronics servo interface PCB assembly bearing part numbers 501-03882-00 and 502-03092-00, silkscreened directly on the board. The Giddings & Lewis brand logo is printed on the board face. Serial number C88366 is visible on the barcode label. Date stamp 41·96 is visible on the silkscreen. The board is configured with two servo channels labeled FDBK 1 and FDBK 2, with signal groups including COS, SIN, IND, RES, and DRV CMD connections along the left edge via a gold-edge card connector. A second gold-edge card connector labeled MACH CONN is located along the right edge with numbered positions to 24. Two TO-3 package power transistors marked H9636 and LH0101AK are mounted on heatsinks on the board face. Active ICs include LM1458M and QM378B (x2). Precision Dale resistor networks are visible. Trimmer potentiometers labeled GAIN, BAL, VR1-1, and VR1-2 are blue multi-turn style and are accessible for adjustment. Multiple test points are distributed across the board face. The board uses through-hole construction throughout. This assembly is consistent with resolver-based analog servo interface applications used in Giddings & Lewis CNC machine tool systems. Physical condition shows signs of prior installation and use.
