In Reply to: Speed accuracy on vintage belt drive TT with "electronic speed control" posted by JoshT on January 13, 2017 at 23:02:46:
So, with the benefit of a good night's sleep, I tinkered ever so slightly with the pitch adjustment nob and am now at a stable average speed of 33.26, which is within 0.2%. It did take about 20 minutes to gradually climb from 33.16 to 33.26, but then it held firm for about another 20 minutes before I turned it off. I'll give it a few more whirls throughout the day to see if it consistently performs that way. And I'll try with a record on it too, which I guess would also verify if the speed control is working as it should.I will definitely clean the belt and applicable surfaces. And I'll also at least give the pitch adjustment nobs a full twist each way a few times to see of that has an impact. Seem like good ideas in any event, and might improve any wow and flutter? (Though I don't hear any.) As far as the internal electronic adjustments, I just don't dare try on my own, but will check with some friends to see if they'd be comfortable trying with me hovering to learn.
Finally, where would one purchase a belt these days that would safely be within spec and do no harm? Also seems like a good investment, even if only for the future.
Thanks again gentlemen, and I'll report later in the day whether I find any notable changes after performing the additional tasks!
