The 939 sounds nice. The current bid is up to 80 dollars. The 737 I bid on is only 35 dollars so far.
Comments on the 737 from the seller
I have owned this
awsome reciever since 1975, it is in perfect working condition and cosmetically perfect, no scratches.
When I just went to take a picture of it, I noticed the diode that makes the station indicator light up is out. Perhaps you can fix it. It is in otherwise excellent shape.
(does anyone know what the cost would be to fix the bad diode.)
