Luckily I can read German and donor machines could also be a Sony TC 440 and Sony TC 580 which have the same chip.: Y6 L5 q. L( c2 ?

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.* B ]+ x5 N: g% z4 N3 L
This will help all Sony R2R users in the near future as well as our machines age over time.
