Sumiko Premier MMT Arm VTA?

Spindrifter, really weird; I have owned two of the arms and both were the same, with a set screw on the collar that attaches to the turntable base that the arm shaft fits into. You are in a pickle, but Tom made excellent suggestions. One alternative is that, as the arm takes a universal headshell, someone used to make one with a little hinge at the back that would allow you to cant it foreward or back. I don't think that it was the Orsonics, maybe Tom will weigh in again with the maker. It is an inelegant but simple solution.

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

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

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??

Spindrifter, that's what this forum is for, helping one another. The Shure is a really great cartridge, very underrated in audiophile circles. I like the felt mat too, the only contender here is the Ringmat, which sounds different, but not necessarily better. How about swapping out the headshell leads for the aftermarket ones offered by Audioquest, cost is less than $20.00. A new arm cable will be a big benefit too. Nice ones can be had on this site for under $100.00. I like the Van Den Hul, other nice ones are made by Cardas, Audioquest, Tara, etc. Changing the wire will be a big deal. Some like to replace the feet with threaded tiptoes. This may or may not work. There are some nice aftermarket headshells as well, such as the Orsonics mentioned above. Well, how about a free tweek? Take the headshell off of the arm. You see that little rubber gasket at the collet end of the headshell? Remove it and put the whole thing back together. Don't worry, you can always put it back if you don't like the way it sounds. You may have to adjust overhang and tracking force, but not by much. Tell me what you think. The change in sound is really profound, but you may prefer it or not.
