Default SP-600 Tuning Backlash

Richard,
I was the guy that had the SP-600 backlash problem.
The solution was indeed the pre-loading on the front
of the tuning cap. Actually, the ball bearing that the
adjusting screw hits was rusty causing a lot more friction than
usual. When changing direction while tuning I could see the
spring spiders flex, which led to backlash.

Steve
