Anyone still using a Teres table?

I have a Teres from the beginning diy era. It has a thick acrylic platter with the great clamp and I run a well tempered 12" arm. 
When mine is running the motor speed fluctuates very easily, it almost feels like if I breath on the platter it will drop. 
Upon research I ran across some mentions that there was a simple mod to the motor/controller to rectify this but I couldn't find any more detail. Can anyone enlighten me further?
i love the table and feel it has a ton of potential if I could get this sorted. 

Anybody have any contact info for someone who could help??

@analogluvr,
In my post on this forum dated 1/1/17 (first post) my last paragraph that starts with BTW, I make mention of two Audiogon members that own Teres turntables and are extreamly knowledgable. If you have not done so yet, message them through Audiogon. My guess is they can either help you or make some suggestions.

Ok I will try that, thanks. 

The Teres Verus motor is very expensive. I wonder if anyone has seen a second hand motor for sale...
