With these parameters, it's easy to create an arc protractor using Conrad Hoffman's program. Japi Roelofs wrote:There aren't many specs available for the 701, but given its 222 mm effective length, and 25° 20' offset angle, I think it's safe to assume they are the same as the ones for 1219 / 1229. What matters is reducing "inner groove" distortions and cleanly tracked grooves where it counts the most. just because they are led to believe it matters. To heck with that annoying "outer" measurement that is so talked about, it only confuses people and creates frustrations that to me are silly and obsessive, and not really even heard. So at the last groove diameters of around 60 to 70 millimeters from spindle center, I insist on a perfect 90 degree angle of tracking. I consider overall geometry of the tonearm, but put most of the consideration on those inner grooves when I set up a cartridge. This allows more "leeway" for even an elliptical stylus to be "off centered". The outer bands of a record are far less "crammed" - high frequency content is "spaced out" farther, and at a faster rotational speed. This part of the record will naturally be the toughest area for a stylus to track.Īnd elliptical styli in that area really need to be as close to zero tracking angle as possible to cleanly negotiate those grooves. Going by the facts, it's true that the small, tiny, high frequency groove modulations at the end of a record, are crammed together at a slower rotational speed. With that in mind, I am still unsure of your meaning. I would assume that you also gained some useful information from others, so I doubt that you're comment is in any way dismissive. It has been a pleasure for me and hopefully to others as well to learn a few new tricks or alternative methods offered by V.E. Of course, others will chime in endlessly.
