Anyone experienced speed issues with Artemis Labs SA-1?

Hi guys.
I was listening for several hours and then out of blue on the last record the speed started slowing down and back and then down again. I had zero issues in my 2 years or so of ownership. Used in an all Artemis lab system.

I used my cell phone to measure (after stopping and removing the record) and it showed around 32 rpm first which then - after a few revolutions_ dropped to 30.
Wondering if anyone had the same issue and figured out the fix.

no it is actually the TT unfortunately.
I use the Eagle/Roadrunner from Phoenix Engineering with one of my other TTs. I know exactly what the difference is on the app and the actual rpm. The app was just to assess the drop in rpm which is about 2.0 change. Extremely audible change and slooooowing down of the music.....

Thanks for the suggestions 
just for context I have 8 TT - two are DD, 3 belt and 3 idler ...
Each has its own strengths and signature sound 
The Yamaha GT-2000 is great (full Yammy stack) A’s is the Garrard 401 or 301
the Artemis is part of a full Artemis system and it works well when running correctly- given that the belt is an actual R2R tape with a tensioner it is different from the VPI or Fairchild 755...

thanks!
It was weird as it happened after a few LPs.
I did not listen since then, but checked the speed with the cell phone app and it did not drop.
I will listen tonight again and see if it will re-occur.

well I was very excited that the low speed disappeared during my next session a day or two later. Then of course after 3 LPs it came back...not sure but perhaps it is the power supply acting up?

Thanks!
Will check it and report back.
I hope i don't have a motor issue - it is a rare Swiss motor as I understand it and was developed for the TT. 
I hope not.

Checked the pulleys - no friction. Not sure about the bearing but does not seem to have an issue.
After 6 full records I had no issues whatsoever. Hopefully this was it.
If it comes back again I may do some deeper investigation.

sorry to hear that.

I think I will take mine in a few weeks time for some check-up...

No worries I do appreciate the advice
i do spend a fair amount of tinkering with my Modded Lenco 78 - to your point 

I had zero issues with the Yamaha though 

Let’s hope we can fix this Artemis table as I really love it - not to mention the Schroeder arm on it
