Luckily I can read German and donor machines could also be a Sony TC 440 and Sony TC 580 which have the same chip.

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., M* G) ?. B+ ]7 x, v3 i) _  v
This will help all Sony R2R users in the near future as well as our machines age over time.
