Yes, brush down, you add .5 grams to tracking weight measurement, move brush up for measurement: measure 2.0 grams, brush down, you will get 1.5 grams. (Shure calculated that the brush pushes up .5g)

Thus you set anti-skate at 1.5 grams, not 2.0.

I use the blank side of an LP to set anti-skate visually, you can check it when playing a warped LP with the brush dn, re-check when playing with the brush up, the majority of the time. Don’t trust the anti-skate dials, you will find that they are not accurate most of the time.

Down for anti-static even if LP not warped? You can check, see if it makes a difference, if so, play with it down, make above measurements

Hudson Hi-Fi Turntable Cartridge Alignment Protractor Mat (Single-Sided Print, no Strobe Included)

I went for the Jico SAS with Boron cantilever for my Shure V15 Type 3. Sounds great to my ears. Tracks like a dream. I am using a vintage Pioneer 707 table and am getting excellent vintage results. It sounds just like I remember the hi end systems sounding in the 70s.

I am using the Jico Boron SAS stylus on a Shure V15 IV, and find it a very satisfying replacement. Measuring the response with pink noise and the REW RTA, I am able to get a very flat response. Tracking is good, although not quite as good as with the original stylus.

With all respect to Elliot, who is a knowledgeable Audiogon contributor, I'm not a fan of using a brush mounted on any cartridge, for the following reasons:

1. it screws up the geometry of the cartridge and makes azimuth adjustment almost impossible. This wasn't a major factor when the V15 series was first introduced, but it is now.

2. Some turntables, mostly belt drives with "low-noise" (aka low powered) motors will not spin at the precisely correct speed with the brush attached.

3. Unless the brush is cleaned often, your you will hear more noise as dirt get accumulated into the grooves. It's a resolvable issue but it's also a PITA.

4. In dry/low humidity conditions, brushes can build up a considerable amount of static on the record surface, also contributing to noisy play.

Best to skip the brush, IMO.

br3098, On balance, I wouldn't use the brush either.  But if your motor is THAT weak that the brush slows down the platter, then we are in trouble.  Most weak motor BD TTs are designed with massive platters; the designer wants the inertia of the platter per se to be the major factor in holding constant speed.  I would have thought that properly designed BD TTs with motors that are intentionally weak would not be affected at all by the brush. Have you had the opposite experience? On all other points, I agree, except as regards the importance of azimuth in the good old days.  I guess you are suggesting that elliptical styli are less fussy about azimuth. The other factor is that most of us never thought much about azimuth in those good old days, because we couldn't adjust for it even if we had.
