Parting out Harmon/Kardon CD 391 cassette deck. Here we have the Rotation Sensor P.C. Board with Sensor in working condition. Unit had failure in power supply circuit, but was playing and recording until then. Reels were in working condition when removed. Which indicates that this circuit board was working correctly. This P.C. Board is also OEM for HK CD491, both models have the exact same transport with the exception of the heads. This board mounts on the rear of transport with sensor observing rear of take-up reel. Used for memory and positioning. Please check pictures. Shipping $8.00, will combine shipping if interested in other items.
