analog newbie question/vinyl weight

Yes Doug i guess i m being just a little to anal on the scientific end instead of the end that counts
let the force be with you Luke.

Kind of tough to measure with most LPs having that ridge at the beginning of the LP.

I'm too cheap to buy one.

Yea Dan ed i understand. I guess you know what i m getting at that old subject VTA with different weighted records. I did buy a 5X lighted magnifying glass to get a better look at the position of my stylus.

We all know when dialed in VTA can make the difference between very nice sound and most excellent sound.

Well to give you a very good estimate based on several years of routinely performing these measurements on over 1000 LPs, see below.

100 gram = 1.00 mm
120 gram = 1.20 mm
150 gram = 1.50 mm
180 gram = 1.80 mm
200 gram = 2.00 mm

These numbers are approximate but consistently close every time they are checked. I have a set of calipers modified specifically for this purpose. I'm actually impressed that the numbers are mostly consistant.

Of course there are a couple that fall outside the norm (+/- 0.05 mm).

Dre your information is very much appreciated and thanks
