Hi Harald,
I have also been using a CSP-170 for a few weeks and have read your comments with interest. Which Mixmaster do you use? The one by Michael P. Bedesem and Etienne Volbragt (v19r1)?
I would be very interested in your file Yamaha CSP-170.txt. How is it structured and what information from the data list was used?
It would be nice to know something about it
Best wishes
