For your consideration, here is a Sony Microcassette Transcriber M-2000 for parts or repair, serial number:  0538420, made in Japan.  It has some wear on it.  I tested it out some.  There is some kind of a problem with the Control Unit plug, where pressing the foot pedal does not work.  I had bought a few transcribers and have tested them.  I know the foot pedal was good.  Item pictured is the actual item up for sale and comes from a non-smoking household.  (167.36j-2.9bb)
