Measure My Turntable Speed

I do have the KAB Strobe and disc. I am not 100% confident on its accuracy. I used Feickert's Adjust Pro + and his test record. When Adjust tells me I am dead on, KAB says otherwise by a significant amount.

I ended up using a Fluke DMM and measured the 3150hz tone on the Adjust test record after communicating with Feickert. He seems very confident on the accuracy of his test tone frequency.

The KAB strobe disc is worth every penny. People who discourage that are those never had a speed accurate turntable. Get it.

I don't by the KAB results. They didn't make sense. When I fine tuned my Bix motor, there was no sweet-spot. It just didn't feel right, whereas now I can test with the record on and needle in the groove during playing. I got my digistrobo for maybe $20 more than the KAB. No-brainer.

It seems the old mentality of must spend lots of money in order to get good results has overcome logic again. Get real here. The powergrid line frequency is very tightly controlled to 60 Hz. Just google it and you can learn how accurate it is kept- to within 0.15 Hz. That is an error of just 0.25%. Probably less than the wow and flutter of many turntables.

Now go out and buy a cheap $100, give or take strobe light and tell me that it is accurate to within 0.25%? No way!

I laugh even more when I see someone looking at a digital readout and believe it to be accurate to the display's 2 decimal places.

OK, I have to speak up here as well. I pondered this same question a while back and found via the grape vine a great and cheap solution. I bought the Wally tools and tried the Cardas LP and frequency measuring via the test meter. My TT was running fast and I was trying to correct it via this approach. So, the problem was that the LP had a slight tendency to increase or decrease in the frequency tone due to a warp or LP pressing issue. So it was either right on or ever so slightly fast. I then contemplated buying into another method such as you. Then someone suggested buying a Digital Photo Laser Tachometer from Amazon. It worked great and cost $20, with an accuracy of +/- 0.05%. Plus you want you can play an LP for stylus drag while you measure. This is the only way to go!
