Default Dual 621 turntable fix

With the arm, not the cogging!

For those who haven't encountered it, the putty trick is to wrap a
thin donut of Mortite, 3M Strip-Calk, or plumber's stainless putty
around the tonearm's shaft. If you do one halfway down the shaft and
another 1/3 of the way from the headshell to the pivot, it helps damp
down nasty resonances. You don't need much putty; if you make the
donut from a piece of unstretched Mortite (about 4mm in diameter)
then, once it's on the arm, flatten it out, you'll be fine. Of course,
the added weight will mean you need to reset the tracking force.

This won't be necessary on a really good tonearm, but on a less
stellar one it can help a lot with damping nasty resonances.

Peace,
Paul
