I bought this one from a audio-dealing friend and I knew it needed work. It needed a new re-wind belt (old one turned into goo) and some O-rings to replace the rubber on some wheels for fast forward and re-wind. It looks a lot like the 3585 but it has some enhancements like an idler wheel between the motor and capstan wheel and a tone control. Once I got the mech running smoothly it actually sounds nice! Not much hi-end (it is limited to 8.5kHz) but it still is nice to listen at.
This one is actually done at the moment… I think it works just as it should. 🙂
