OK, I've got the speed dialed in, and it runs dead on at both 33 1/3 and 45 rpm.
It will eventually start turning by itself at 33, and starts right up at 45. The triac controller cuts off portions of the AC sinewave to the motor, so the actual speed control is just loss of pushing power.
I asked my daughter if she wanted the speed control mounted where she could adjust it, just in case she did. She was horrified at the idea. "Keep it looking original, Dad!" 8) That made me smile. Yes, I've made some alterations to it "under the hood," but it still looks like it came on a time machine from 1954 and works better than it ever has before.

It's not how bad you mess up, it's how well you can recover.
