The distance from the center of the platter spindle to the vertical axis point of the . alignment geometry. Well....you'd think it would, anyway. When is the day going to come when MF fesses up and admits that anything we 'hear' while operating our ears in trust mode, is valid and useful for one person in the universe, and only one. I have read 222, 227, 228 and most commonly 230mm. Or the effective length of the tonearm minus the optimal stylus overhang. The second point at which the cantilever is tangent to the groove is the “outer null point”. Spindle centre to horizontal pivot point of the arm. For the most part most of my questions have been answered, and I am no longer in semi-darkness. That was meant to be a reply to Avanti1960... about the linear trackers and their other design challenges. The Garrard "Zero" was another attempt to eliminate tracking error; the concept is valid but the execution was poor. I pulled out your DVD on TT setup and plan on watching it (again) for a primer. as long as the cutter truly is tangential then a linear design has a fighting chance. when the tonearm mounting position is adjustable then when a cartridge has a non-standard relationship between the mounting screw holes and stylus position the arm can be moved to allow a proper overhang. It was designed to use a cartridge with mount distance to stylus of 9.5mm. When you use a gauge or protractor to set the “overhang” you are setting it at one of the two “null points” and possibly confirming it by also checking the second one. I bought it new back in 1983 and it was supposed to be the latest thing. If the pivot-spindle distance … Friction produced by the stylus coursing through the grooves creates a drag force along the dashed/maroon line. Therefore, if I find the overhang measurement is it going to determine the exact distance, and angle for this Sony tonearm? Note: these data, and our alignment tool, are optimized for 12 … Cutting heads move in a straight line, along a large screw. Graham Engineering has been making tonearms since the mid-80s. The WallyTractor Universal is the cartridge alignment protractor that features arcs specific to the tonearm you own as well as tonearms you may own in the future. maybe there are some patents against the application. Of course there are numerous possible alignment geometries (Loëfgren, Baerwald, Stevenson, UNI-DIN, etc. In the next steps, the armwand is installed, the tonearm alignment gauge is placed over the ’table spindle, and the cantilevered armboard of the ’table is moved until the leveled armwand attaches properly to the tonearm alignment gauge over the ’table’s spindle (see manual). The heart of this new design is the unique 4-point bearing. Make sure you have all adjustments initially set as specified in the manual - including Anti-Skate; too little of which may cause the tonearm to fly to the spindle. Why? I have a Luxman PX-101 linear TT that has been down a while. all i know is that on my table it's easy to tell when the cartridge is passing through the null point regions. You've been trusting your ears again. If you buy a used ‘table that’s been pre-drilled and fitted with a secondary manufacturer’s arm, it’s a good idea to check the P2S distance either by using a protractor that has a measuring beam (Feickert, Dennesen, etc.) So now even I understand this! The distance from the center of the platter spindle to the vertical axis point of the. The needle would come down acting like it would go through the record, but then land gently. Set-up......what set up, the only thing you could adjust was platter speed. It has been described as powerful and dynamic, solid yet expressive, delicate and tactile. Or the effective length of the tonearm minus the optimal stylus overhang. Spindle centre to mounting hole centre (normally the same as pivot to spindle distance) Pivot to spindle. Then I asked about the distance of the centre of the platter/spindle to the tonearm's centre point. Oil damp system equipped, and this main purpose is to improve bass performance, and protect record disc damage from jumping stylus. And that was common on Shure cartridge. Overhang: The distance past the spindle center-pin the stylus will be when the tonearm is rotated over the spindle. tonearm. the 222mm mounting distance for a Rega tonearm is … https://www.ebay.ca/itm/Sony-turntable-tonearm-with-Cable-In-Excellent-C...
