Sorry — just seeing this now.
Usual speeds were between 32-38 Rpm. I’ll usually key it off any AC line hum there might be.
There is no technical difference between red and blue belts, simply when they were made. Red belts were made until 1964. Blue belts from 1964-1975. There were also purple belts until 1980.
Hope this helps.
