Luckily I can read German and donor machines could also be a Sony TC 440 and Sony TC 580 which have the same chip.( S* y. r# c0 M. q; E% t
A rare Sony turntable TTS 400 has the same chip used as well.

I got some of my Dutch R2R friends to have a look at it as well and with a bit of luck they can design a circuit with disrete components.
