Well, I do remember my reasons for starting to do this. There are two. The
first was common complaints of repetition problems, traceable to the fact
that the capstans were set too high. The second was that enough settling
occurred in the next year or so that it was necessary to re regulate the
capstans if they were adjusted to relieve the complaint from reason one. I
assume that these capstans are left high in the first place because of
reason two. Trouble is, that had the secondary effect of producing reason
one. Since I feel that the immediate customer complaint has priority
(within reasonable mechanical limitations) over manufacturers' allowances
for anticipated settling, this gets everyone off the hook without wasting
time duplicating effort after the action settles down. One nice "feature"
of my dodge is that it's nearly instantly reversible. Any other tech who
happens along and sees what I've done can restore the original capstan
adjustment and repetition problem to like new condition by pulling out the
bushing cloth. It shouldn't take more than 15 seconds even if he drops his
tweezers twice. 

So what do you tell customers with new Yamaha verticals who complain about
repetition problems to get them to put up with it until next year? Mine
don't want to hear that.
