Turntable weight affects speed


I tried a Thorens tt weight on my Thorens TD-850 belt-drive tt. It noticeably slowed it down.  It seems like extra weight on the bearing would affect any tt, but what do I know?  Is a speed control (and strobe/test pattern) generally required to use a turntable weight while maintaining the proper speed?

But aren't you just increasing the speed (power to the motor?) to compensate for the additional load? I wonder if that will overdrive/overheat the motor and impact its longevity. 

Agreed, increasing the load might be detrimental. Lightweight Origin Live “weight” is on the way. 
 

thanks for all the ideas.

On belt replacement, 

I use two belts on my table. Every six months or so I drop them into a pan of boiling water for about twenty seconds, this "un stretches" them a bit. After drying, they go into the zip lock with baby powder in it, then shake them off and re install. I get a lot more life from them this way.
