Condition: For Parts or Not Working
This Mitec MC3719A 1:1 Local Control Unit is being sold AS-IS for parts or repair. During our lamp test, only the AUTO and MANUAL indicator lamps illuminate — the remaining indicators do not respond as expected. The unit is not confirmed functional and is not guaranteed to operate correctly in a system. It is offered as a source of useful parts or as a repair/restoration project. Externally, the chassis shows typical wear consistent with rack-mounted service use; the front panel labeling and connectors appear intact. Two rear IEC power inlets and the multi-pin D-sub and DB9 connectors are present. Please view our photo set and contact us if you have any questions.
