Rpm's and The Strobe


What do you think it means when the strobe indicates the speed is correct but, in actually counting the revolutions in one minute I came up with 30 more than once??? The music sounds fine I do not hear any pitch changes...

It means that it running at correct speed since the US is a 60 hertz country.
It means you need a Phoenix Eagle and Roadrunner. Eagle is a highly tuned power supply for tts, Roadrunner is a real time tachometer.  The two units coordinate to lock in rpms to within .005/minute. 
I have no affiliation with the company, I'm just a very happy customer. 

Cheers
