For vintage DD tables I look no further that Victor, better known to most as JVC.
My TT71 motor drive unit is a beautifully crafted and precise operating DD table that uses a DC motor. It's a 12 pole, 24 slot DC brushless motor with a frequency detection circuit that uses a 180 slot frequency generator yoke with a magnetic disc and a printed circuit board with 180 coils printed on it. Needless to say, speed is very accurate and wow and flutter is very low.
Most folks don't realize that Victor invented the modern quartz locked direct drive motor system. Victor was a engineering company that shifted it's focus from audio to video in later years and became leaders in that field as well. Victor supplied motor drives to other companies as well, Micro Seiki being one of them.
