RoyLCraft custom Technics SP/SL-1600MK2 Turntable

Czarivey, your post makes no sense. The SL-1600mk2 / SL-1700mk2 / SL-1800mk2 have both rubber/felt feet and a spring suspended tonearm and platter. That is vastly superior to the hunk of rubber that the SL-1200mk2 sits on in terms of sound and shock isolation.  

The auto-return mechanism is robust and uses optical sensors, so it presents zero drag on the tonearm. 

The only thing about the SL-1200mk2 that is redeeming is the basic accuracy and stability of the drive motor and tonearm bearings, which it inherited from the SL-1600mk2 / SL-1700mk2 / SL-1800mk2. 

If there is a criticism to be made about the SL-1600mk2 / SL-1700mk2 / SL-1800mk2, it is that leveling the suspension requires some patience. On the other hand, the SL-1200mk2 is so simple that even a rapper can use it. 

isolation of 1200 vs. 1600 is same thing as isolation vs. none. that's where sophisticated 1600 and further loose big time.

the SL-1200mk2 is a dumbed-down derivative of the SL-1600mk2. Technically, the SL-1600mk2 / SL-1700MK2 / SL-1800mk2 are a more sophisticated platform from which the ruggedized SL-1200mk2 is based on. The SL-1600mk2 has a vastly superior double-isolation suspension system, automatic play and automatic tonearm return. The SL-1200mk2 has exactly the same tonearm, motor, platter and drive control, mounted in a rubber base. 

I've owned a few. Sophisticated and troublesome turntables. Cheap version of SL1200.

which belt? it has direct drive tonearm belt?

Tone arm drive belt.

Do you own an SL-1600MKII?  

which belt? it has direct drive tonearm belt?

SL-1600 is very troublesome turntable.

Not sure what this means. 
My SL-1600MKII has been working for about 30 years.  I had to replace the belt about 5 years ago, and its still going strong.

That's why I asked if anyone knows anything about this.
