Vacuum Record Cleaner Rreplacement

@orthomead 

Sooo, here's the million dollar question-how do those of you who finish with vacuum drying eliminate the static charge and the dust Kamikazes?

Those Kamikazes appear from nowhere (or from me and my clothing?) after air-drying, but I can usually gently blow them away.  I play the record before sleeving it, and use a conductive brush before play, but ...

I've got another million dollar question.  Does the mere act of playing a record create new electrostatic charges?

The triboelectric effect creates electrostatic charges when dissimilar insulators are rubbed together.  Diamond and vinyl are dissimilar insulators.

Do these charges create any audible noises?  Or do they attract charged dust mites which in turn act as audible obstacle courses for the stylus?

The answer to your first question was answered many years ago - Phonograph Reproduction 1978, James H. Kogen, Audio Magazine May 1978 Audio-1978-05.pdf.  However, simple carbon fiber brushes unless connected to a ground will not dissipate static from the record.  If there is a static charge, the record will have a negative charge, and particles are mostly positive charge, so they attract to the record.  Absent a static charge particles should not drop on the record since the air current will draw air down and then across but above the record - Laminar Flow Over a Spinning Disk | Ansys Innovation Courses.  Additionally, particles deposit/drop from the air at different rates depending on the particle-size - CACR25_FINAL_LR.pdf.

Antinn, thank you for citing that 1978 issue of Audio magazine, in which in the section on ES charge, it is clearly stated that friction between stylus and vinyl does not cause significant ES charge to accumulate on the LP surface. Maybe that will finally satisfy RB.

Maybe that will finally satisfy RB

That's wishful thinking!

Compared with a 10-kV needle, significant becomes insignificant!

Shure themselves seemed surprised that they did not find significant charge from diamond rubbing in the groove, but they were comparing with other causes of static like friction with liners.

But it was lovely to go back all those years and see adverts for stuff I still have.

@antinn 

Thanks for that magazine.  It took me ages to get to the Shure article because of all the other great content!  Those were the days ...

I think you are agreeing that electrostatic charges on records attract positively charged dust particles.  We probably disagree on how hard these are to dislodge when they are micron size!

I am getting quite a lint buildup especially with new records.  Is there a chance some of this lint could be vinyl worn from the groove?
