I have one too, and I agree it's an amazing device, but a while ago I discovered it had seized up and stopped working - the fast-forward and rewind had been dodgy for a while, but both of them had finally given up, and playback had also failed.

I replaced the belts, which got playback working again (see picture here https://twitter.com/chris_cannam/status/1043961675114840070) but ffwd/rwd appeared to be victims of a seized pivot which I couldn't get moving. So it plays beautifully once more, but still can't wind.

Might be worth checking that yours is still going ok, in case lack of use is a factor.
