Re: [ARSCLIST] Advice for filtering surface noise

[Steven Smolian <smolians@xxxxxxxxx>]

78 grooves are of no uniform width.  Anywhere from 2.5 to 3.5 mils are
usual.

If you are playing through a stereo cartridge, one source of noise is the
vertical signal on lateral cut records, the opposite for most Edisons,
Pathes, etc.  The solution involves wiring the cartridge proerly or having
the appropriate switch on your preamp, should it have one.

etc.
