Sumiko Premier MMT Arm VTA?

Viridian, you are right, I feel like an Idiot. I set this unit up myself new and replaced the horrible stock arm myself with present one. That was a life time ago and several moves and divorce and mondo memory loss and obviously I no longer have the paper work. The table has been in safe storage for years. I am currently rediscovering my vinyl(from early 60s–late 80s). Any way,I mounted the arm with the set screw at the very rear of the arm base 180°from cueing arm post. I couldn't feel it with my thick,calloused,clubby fingers and had to turn the whole table around for a visual check(now must reset and level).Thanks all for your interest and input. I really like this table and am considering tweaks and such rather than buying a new table, any suggestions?? mats, cones, sorbothane feet,etc, what do you guys like??

Viridian, thanks for your response but I really think that there is not a VTA adjustment on my arm. I believe the arm I have is an early model and the VTA adjustment was built into subsiquent "improved"arms. There are no verticle adjustment set screws anywhere on the shaft base that is attached to the armboard. Is that the area that I should be looking? So now what? I mean it is perfect for this cart. The arm is perfectly parallel when on the record.But at some point I might want to get a different cartridge. All advice and thoughts would be welcome.Thanks
