I think we were referring to the variable speed that we find on individual recordings themselves. There was a time when 33RPM wasn't really a standard...at least, a time when close was good enough to some manufacturers (and I've only seen faster recordings, like 30RPM).

Waxing nostalgically... I probably owned one model of Garrard and Collaro record changer ever built, and never found one off speed if properly maintained. Some of them had variable speed as well.- I forget the percentage of shift. Regular checks with a neon lamp and known accurate strobe disc easily confirmed this. I know this is off topic, but I felt the need.

How about a "variable > high-speed non-vinyl stylus-retrieved audio storage disc?" Because when three-speed changers first appeared the three choices were "33" "45" and "78" whether or not they were accurate... Steven C. Barr
