Measure My Turntable Speed

Hi,

A simple strobe chart and a fluorescent light will do the trick nicely.

Mosin,

It will work, but not be nearly as accurate as the KAB. If the light is locked to the incoming line frequency (50 or 60Hz), and the incoming line frequency shifts ever so slightly (which it does all the time, not by much of course (maybe +/- .2Hz)), but enough to be significant to a turntable's accuracy), you can see how the problem arises. You are now using your flourescent light (which may or may not be at the correct frequency corresponding to your strobe disc) to set the speed incorrectly. The power line is no place to look at as a point of reference!

The beauty of the KAB is that it operates off a battery - and it is easier to read than a garden variety "60Hz" strobe disc because of the higher operating frequency. All in all it is a very accurate device, and a worthwhile investment.

I never tried that method, but it sounds correct. I guess several HI FI test records have those test tones. So a test record could be found in used record bins. Since you feel confident in reading a meter, give it a shot and let us know.

The KAB is easier to do and work with while doing speed adjustment.

sounds like i should just get the KAB...will probably do that.

I understand that the Digistrobo works well too.
