Hi, did a quick Google and found this link on a German Forum regarding the CX-032B chip.

Luckily I can read German and donor machines could also be a Sony TC 440 and Sony TC 580 which have the same chip.! w( y+ i# L6 E' C% [) |/ j
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.7 d* |4 D- r( I2 X& |
This will help all Sony R2R users in the near future as well as our machines age over time.
