Hi, did a quick Google and found this link on a German Forum regarding the CX-032B chip.
% e% A; c" ?8 ?9 K+ A# {! I0 Q9 `; r* x! w) l3 `
Luckily I can read German and donor machines could also be a Sony TC 440 and Sony TC 580 which have the same chip.9 b5 C9 A, _7 m
A rare Sony turntable TTS 400 has the same chip used as well.

This will help all Sony R2R users in the near future as well as our machines age over time.
