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, just love that deck of cards solution!!!!!!What a time and temper saver.

Viridian is right, but the access to the set-screw adjustment is hidden unless you know where to look. Look at the outer rim of the MMT's mounting base, about 30 degrees counter-clockwise from the cue device indentation -- you'll find an unmarked HOLE. The adjustment can be accessed by an Allen (5/64, I think) wrench. Caution, the arm will drop as soon as you loosen the set-screw.
Best of luck,
Joe

If it has no VTA adjustment, and you don't want to get another arm, then you have only one option, and that is to make machined spacers that will fit between the arm board and the base, that will be the correct thickness to raise the VTA to the proper level for that cartridge. This really allows only one VTA because it is too difficult to keep changing these for small variations in record thickness.
If the new cartridge has too much VTA, then you can use spacers that are available to fit between the cartridge and the headshell.

I suppose also you could use a spacer disc under the record mat,or different thicknesses of record mats to do the same thing as the headshell spacers, if the TT allows this.

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
