Can't help with the speed control beyond what the others have said.

I changed the worm on my 8D644 probably 20 years ago. Massive job not to be undertaken lightly, I suspect no-one at B&H ever thought it would need changing. I didn't want to repeat the experience so directed a friend to have his identical machine done by a repairer (not the one listed above). When the machine came back I wondered how they'd dealt with a particularly hard to access bolt I'd struggled with. The answer was simple - they hadn't refitted it!

My machine has the AC motor and ran fine for many years, but has lately started to suffer from wow and my attempts to trace this have failed so far.
