Up for sale is The Fisher MPX-100 stereo multiplex adapter.  This unit is complete and in nice condition.  All vintage tubes.  I no longer have a tuner to test this with. Last time I tested it a year or so ago it was working. Sold as-is with no guarantees since I cannot currently test it.  I plugged it in though it does fire up.

This is a very clean unit.  Chassis is in nice shape and has no corrosion.  Face-plate has some discoloration which may be able to be cleaned off.

Please take a close look at my feedback...Sold many vintage electronics with nothing but satisfied customers!
