That's a good point.
A general question, since I've only worked on cart machines, tape decks and turntables with hysteresis-synchronous motors: A couple of engineering texts I have indicate that such motors, particularly in the smaller sizes, may not need a cap to start as there is enough of a "kick" to push the motor into rotation with just applying power to it. Is that true with the kinds of motors we see in old mechanical devices?
P.S. If you have the actual manual for a CB-77 or any of the CB series (like the 16" transcription monster!) I would love to have a scan for the catalog section of the below-mentioned website. I have the CB series sales brochure, but no manual.
