Measure My Turntable Speed

I've been told that a very accurate way to measure the speed of a turntable is by using a test meter set to khz, placing the positive terminal into one of the outputs of the phono stage (or tape output), the other to the ground and then play a 1000hz test track of our a good quality test record... If the table speed is good, the reading should be very close to 1khz...

Ever tried this one?

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.

Laser tachs are used to check the mechanical tachs of airplanes. Typically used at 2500rpm. I doubt they would be useful at 33rpm.
