Turntable speed accuracy

Quite right Lew.
It really doesn't matter if your TT is revolving at 32.4rpm or 33.3rpm (other than pitch)......as long as it it is unwavering!
And that article you read was the one I posted by Peter Moncreif of the IAR. It was like a thunderbolt for me. The man is a real thinker :^)......in a field where there are some stinkers :^(

The turntable speed should be at least as accurate as the tape recorders used to record, master, and playback the tape.

Constant speed is "much more" important than absolute speed.

Just buy a strobe disc and illuminate it with a light bulb.

The 60 Hz AC frequency does not fluctuate enough to worry over.

Adjust the speed of your turntable, or AC input (if you have a variable frequency supply like VPI SDS) for the lines or dots to appear stationary or slightly vary around a fixed position.

This is simple and more than sufficient. Tape decks are not all that accurate, and do go out of spec.

On my VPI TNT the SDS AC line frequency is set within .01 Hz.

If your platter is heavy, playing a record will not affect the speed.

Sutherland designs "CRAP" cold sounding phono stages!

They sound similar to HALCO amps!

The turntable in the video has a wimpy low torque motor drive system!!

Needle drag does not slow down well designed turntables!
