Hi, did a quick Google and found this link on a German Forum regarding the CX-032B chip.# X6 O$ C* M7 x: G# k

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.8 q3 f( [: ^9 |/ X- C* k
This will help all Sony R2R users in the near future as well as our machines age over time.
