Measure My Turntable Speed

Why worry about $90 bucks when entry level carts cost $1,500 a pop to strain gauges $6G to $14G. Even if your a Grado moving iron type the KAB is easy to use with repeatable results. Should you be happy with your speed system so be it. Most of the time record care and reasonably good AC sources resolve most speed issues. Record care ? A clean recording spins well and has less grunge , a "mother's helper" to the ears.

"Reasonably good Ac sources" is to be understood as line controllers; VPI, ProJect, Walker,etc. "AC sources" also includes dedicated lines for analog, pre-amp , amp & speakers should they have active AC sources. In this situation one hand washes the other. If you are 'ol school and are agast at those recommendations, no problem. But turntable speed is a measure of many things , not soley lights and paper rings.

Probably an overkill, but depending on your TT, a LYS gyrascope might address your needs. I use it as both record weight and speed gauge on my Platine, and it's fantastic.

Anyone tried these laser Tachometer in Ebay? They are very reasonably price (~$30) and let you measure the RPM with your record/clamp in place?

I am going to buy and try one to see how good these things are!

What kind of TT are we talking about? If it is direct drive (no belt to slip) with speed set by a crystal oscillator the TT is probably more accurate than any device you can buy to measure it.
