[78-L] stylus for vertical-cut Edisons

[Dave at Audio Tech Transfer]

I'm using a Stanton 500.V3 to play vertical cut Edison discs on either my
Technics SL-1200 (with 78 rpm mod) or a Technics SP-15.

-3.0 or 3.5 mil stylus works fine.  I don't think this is a critical point,
after all, you just need to ride the bottom of the groove.
-Set antiskate so that there's no drifting of the tonearm in either
direction.
-Adjust pitch to + 2.2% (80 RPM) for Edison discs.
-Switch Blue & White cartridge leads as follows:

Blue (headshell wire) goes to White (cartridge pin)
White (headshell wire) goes to Blue (cartridge pin)

This nulls out the unwanted horizontal signal of the stereo Stanton
cartridge, while capturing the vertical signal.

I've got a separate headshell and cartridge (wired as above) that's labelled
"VERT." on the underside of the headshell.  So it's an easy matter of simply
swapping cartridges anytime I want to play a Diamond Disc.
