Turntable Speed

tgyeti. there is a strobe pattern on the bottom of your platter and you are seeing it through a prism. Older turntable drive systems could wander a little so having a built in strobe was handy. Some people also like being able to match pitch. Modern turntables tend to avoid strobes either because of the added expense or their advanced drive systems are always locked in to the exact speed. Some modern tables display the speed electronically by reading a magnet or light strip on the bottom of the platter. The most advanced systems read the platter then maintain exact speed regardless of the drag exerted on the platter.

Is a phone safe on a turntable doing 78 rpm?  😊

Tried the app. I get 33.39-33.41 on my Pioneer PL-630.

ibmjunkman -- Thirty-three-and-a-fourth. Scandalous!

@edcyn:

If the speed is way off, you should maybe buy another turntable with speed adjustment possibility.
