One more note on using anti-static spray on turntable dust covers: Make sure the solution is safe for the type of plastic the dust-cover is made from. Some anti-static solutions use a carrier that melts certain plastics. Also, test a small, unobtrusive section before coating the entire insides of the cover. You may not like the fogging that the anti-static solution causes. If it hasn't melted the plastic, it can be wiped away, leaving a thin coating that is more transparent, and better than no coating at all. Mark Freeman John Fluke Mfg. Co., Inc.

The REAL reason for using the dust cover while playing is to keep off dust. THe aerodynamics are such that the spinning disc creates a vortex that attracts air [downward], allowing it to deposit on the disc surface the dust carried in the air. Whether enough static builds up on a dust cover to attract a tone arm--why not?--depends on the stylus force and the charge buildup on the dust cover. But, shouldn`t the tone arm have been grounded? Why not apply an electrolyte(i.e., anti-static fluid) to the cartridge shell, presumably plastic, to allow charge to leak off to the tone arm? Perhaps another solution is necessary for those fancy boron fibre tonearms. J.Frey
