analog newbie question/vinyl weight

has anyone taken measurements of 120,150,180 and 200 weighted lps in inches curious as to what those measurements really are.

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.

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.

Dre your information is very much appreciated and thanks

One thing is for sure my Triplaner and my ears will let me know when VTA is off. But now that i have your valuable information along with Tri letting me know that 1 revolution of the VTA towers dial is 1/40th of an inch. I can get mighty close with any weight record. That breaks down to 1/40th=0.025 decimal in. That equals 0.635mm per revolution of the dial.

Wow now i m getting real scientific and i know in the end my ears will let me know if i need to make further VTA adjustments but i should be close.

I m retired now and have plenty of time on my hands guys.

Doug the Luke method is the only real way to get it right or i should say get it to sound right to your ears.

I sent in my TP last month for a check up and on return decided to spend the time to listen for those changes from different VTA/SRA settings since i was starting from scratch. In the end my previous settings were high with arm height, and i knew UNIverse likes in low in the back. I listen to blues and classic rock mostly and like a sound thats more on the bright side of things. To my amazement you dont loose that nice tingly sound when you lower the arm instead you get that and better mids, bass, stage and sound thats fantastic/more seamless. The funny part is i thought my setup sounded good before i sent my TP in go figure.

I love vinyl playback with its hands on routines what i needed to learn and after 40+ years of hands on, you should never think you know it all and sit pat.
