Re: [ARSCLIST] lacquer transfer

[Michael Biel <mbiel@xxxxxxxxx>]

I've heard mineral oil mentioned, but I wouldn't want to try it.  It is
messy.  Whenever you use a liquid while playing you are creating a
separation of the stylus from the playing surface which might also be
reducing high frequencies and tracking accuracy.  The stylus is skating
over the liquid film.

That being said, it is important that wet playing only be done on vinyl,
styrene, lacquer, or plastics like this.  NEVER on shellac.  NEVER. 
Shellac shouldn't be played if it is even just slightly damp.  A few
months before the demise of Hi-Fi Stereo Review (I think) there was an
advice column (I'm trying to remember his name, it might have been Ian)
who recommended playing shellac 78s wet.  In fact, he said that he had
found it difficult to play 78s unless they were played wet.  He also
mentioned that you have to frequently clean the gunk off of the stylus. 
Wet playing freed up the dirt in the grooves.  Of course records should
be cleaned first, but what he didn't realize that the gunk was SHELLAC
and that after scraping off a layer of the record itself you have set up
a situation where the record is never the same and can't really be
played normally again.  He had ruined his entire 78 collection and was
wondering how come he had trouble playing them normally.  This
dunderhead had been doing this advice column for several decades and had
also written several books.  I had always thought his advice was screwy
-- I remember one time him not knowing anything about guard bands
separating tape tracks.  

Anybody remember who that jerk was?

Has anyone ever found a coating or spray that can be applied to a 
lacquer to make for a quieter transfer, besides water?

I seem to recall a presentation by Seth in which he mentioned Tascam 
pinch roller lubricant or cleaner as a possibility.
