how to use LDA quartz regenerator??? help

i have garrard 401 and bought this Longdog audio regenerator.   I cant get the platter to be on 33 rpm .   when play a record the music drags of course.   i use the speed control knob and not get it there. Turned all the way to right and still slow.

the directions less than clear to me.   i read them to say use the speed control knob to get to speed of 33.   when i try to use the garrard controls makes no difference.  still slow.

can someone tell me what i am doing wrong please?

Well OP, was it the back toggle speed lock engaged?

If that does not solve the problem, plug the 401 directly into the wall and check for speed. Perhaps your motor needs a rebuild?

How are you monitoring the speed? The strobe markings on the 401 platter are not reliable and nothing beats the Phoenix products now being sold by Sota 

And last, what is the provenance for your 401? Are you sure you have the original motor and not a replacement motor? That is something of a long-shot thought as the LDA should control and change speed regardless of whether the motor is AC synchronous or induction.

Are there no adjustments that affect voltage or current output from the LDA? If so, have you fiddled with them?

Bought a Monarchy regenerator. It would be a reach for me to believe it doesn't help. But then I'm a big believer in cleaning up the power.
