Measuring Turntable Platter Speed


I have an older Rega P2 that seems to warble (for lack of a better word) when playing. It's not that it's fast or slow, but I can hear slight, quick, pitch changes when playing a record. I put a new belt on, but no change.

Is there a method or relatively inexpensive instrument that I could use to monitor small fluctuations in platter speed?

Thanks in advance - Jim S.

I use the Clearaudio strobe disc. I think it is somewhat expensive, but you can use either side, one for standard household lights, or the other side with the optional Clearaudio strobe meter, which is definitely expensive.
