Luckily I can read German and donor machines could also be a Sony TC 440 and Sony TC 580 which have the same chip.3 Q3 a( f9 ^9 P1 x; B5 w
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.+ U3 k+ g5 f, e+ [
This will help all Sony R2R users in the near future as well as our machines age over time.
