I listed an old turntable on ebay, and ended it early because the bidding, IMHO, was out of control. I would have been happy to get $25 for it, and my wife was ready to send it to Salvation Army. There was also a cassette deck and dynamic processer, and the winner does not want them, but all the questions were on the turntable. As it is already sold, here is the link:
Pioneer PL-630 RG-2 CT-F900 Vintange Clearance 1 Owner - eBay (item 220505215259 end time Nov-06-09 05:14:32 PST)
This thing has been in a closet for probably 20+ years, still works. I bought it when I deployed in Korea in 1978, and probably did not pay what it sold for.
I also had a Sansui 9000 receiver from the same era, and it sold for over $500.
What is up with old electronics?
