Hi, did a quick Google and found this link on a German Forum regarding the CX-032B chip.! \$ a, q! @" X8 \! i0 E

Luckily I can read German and donor machines could also be a Sony TC 440 and Sony TC 580 which have the same chip.% M. K; n, O' y$ b5 F
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.  O/ z: E" Z8 O0 h
