[sdiy] Yamaha CS-60 issues

[chris]

I think they simply wanted to be independent from a foreign company.

And, with all respect to Michael and his knowledge - calling this "planned
obsolescence" is ridiculous. Until very few years ago, the "standard"
33xx chips were obsolete too. 
I'm fully aware that such a concept of buy-new-instead-of-repair exists
today, but not in this case.
