Turntable Speed


Hello Forum, I'm getting back into record listening after a long hiatus. Please forgive the naive question, but here it is.  My former 1981 turntable had a speed control with the little window where you could fine-tune the speed if it was a little off. I've noticed current turntables don't have that. Reasons?
Thank you.

Modern direct drives and many belt drives have this feature. That is to adjust speed. May be an integrated strobe or checking with any kind of strobe disc. For the remaining belt driven ones you pray for belts within specs.
Not having a window for checking revolutions mostly a design approach.
This is quite a good app for iPhone and Android to check your turntable speed. Simply lay your smartphone on the platter. Start the turntable and get a reading:
