控制转速的IC, SONY CX-032各脚电压值如图

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." p4 F9 y0 N# k, n# }) ^
This will help all Sony R2R users in the near future as well as our machines age over time.
