The Gettys Manufacturing Co. 66-0139-00 1721OM (Type A00330) is a three phase servo drive amplifier assembly produced by Gettys Manufacturing Co. of Racine, Wisconsin. The assembly is mounted on a fiberglass backplane and combines a primary control PCB, a heatsink mounted power semiconductor stage with three pairs of finned power devices, three commutation transformers, electrolytic filter capacitors, and an integrated power section that includes a four pole circuit breaker, a contactor, and a ceramic high power resistor. The control PCB carries multiple terminal blocks for field wiring, ribbon header positions for I/O expansion, and silkscreen markings consistent with the Gettys analog servo amplifier platform used in CNC machine tool feedback loops. Red high voltage interconnect wiring ties the power semiconductor stage to the bus bars on the heatsink assembly. The nameplate identifies the unit by part number 66-0139-00 1721OM and Type A00330, with the serial number field blank on the rating plate shown. Gettys servo amplifiers of this generation were widely deployed in DC and AC servo positioning systems on lathes, mills, and machining centers from manufacturers that integrated Gettys drive electronics. This assembly is suited to applications requiring replacement of an existing Gettys 1721OM drive assembly or for use as a parts donor for refurbishment of other Gettys platform drives. Buyer should verify part number compatibility with the host control system before installation.
