Luckily I can read German and donor machines could also be a Sony TC 440 and Sony TC 580 which have the same chip.. Q0 j6 P/ N3 A2 t- j
A rare Sony turntable TTS 400 has the same chip used as well.% F- V/ J: n+ F

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.( g# F+ x9 Q2 B1 T
