trying to be more diligent about updating threads.
Further research located an old review of this tt by M Fremer which said there is an internal potentiometer for adjusting speed. It was not referenced in the manual. So I bought the RPM Pro app, opened up the power supply box, made some adjustments: problem solved.
But went ahead and ordered a belt and OL tt “weight”. The app said the wow and flutter was .25, a little higher than desirable.
Thanks to Michael Fremer and all the ideas on this thread.
