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.2 L# G, f+ K& T+ `% c- s, s; T
A rare Sony turntable TTS 400 has the same chip used as well.6 K( f  l& \' P. {, _, D- m0 i& e

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.6 c' M% F0 a( z8 b: h2 _: w. x8 U
This will help all Sony R2R users in the near future as well as our machines age over time.
