First time I've seen that model, Ben. Quite something else for a mid-70's design from Pioneer, but the Japanese-market-only had many pieces that were much more refined than those available for the markets outside of Japan.
Miles: I bought it for $50 which included the hubs, Akai take-up reel and a 10.5" recorded reel of the Beatles' White album. I found the wired remote control for it a few years back. I got about seven years of use from it, before selling it on consignment last year for $1,350.
Miles: I sold a number of my components in 2013, many of which I was the second owner. I may be ready for another component purge in 2015. Yes, it was nice work that you completed on those cassette decks before selling them. If you hadn't tried them you wouldn't have known whether they were keepers, or not.
I found another old turntable at the mini flea market a few weeks back for $20.
