| How to use Feickert Protractor on SME V Tonearm As has been mentioned, any two point protractor can be used to set up an SME, or any other arm for that matter, irrespective of whether the arm base slides, the mounting board pivots, or there are slots in the headshell.The SME approach which is b... | |
| For VPI Unipivot Owners, do you use antiskating? Doug (and Adeep42),Whatever the rights and wrongs, it is not helpful to state that the method Lederman uses somehow negates the fact of what he says about cartridge wear. The "appeal to authority" would concern the fact, if it is true, that: every... | |
| tonearm cable straight through or plug in How do you know production cost is the reason for not using antiskate, and not a different reason like a better design?Because there are skating forces which affect all pivoted arms and omitting antiskate altogether is not good design. Likewise us... | |
| tonearm cable straight through or plug in It is not just simply a question of "straight through" or not. You have to consider the wire gauge. In my experience, the stiffness or lack of flexibility of the wire can affect downforce, antiskate and tracking. Most wires that are advocated for ... | |
| Where to find uni din protractor Fleib,I have advised Rega owners to try a similar alignment which avoids having to slide the cartridge overmuch. http://odysseytonearms.blogspot.co.uk/2011/09/stevenson-alignment.html But as you say, it means more distortion on the outer inch or s... | |
| Where to find uni din protractor Fleib,Did you ever try nulls at say 70 and 124 for lower outer distortion?Thanks for the Uni-Din nulls - I'd presumed they were around that, similar to FR66.Tawa,Do keep in mind that small errors in offset and overhang can lead to big errors in di... | |
| Where to find uni din protractor Hi Nikola,Some more boring stuff...There is an RIAA standard from 1963 (and subsequent later revisions and metrications) which gives the record hole size as 0.286", with a tolerance of +0.001" and -0.002". This means that the hole can be between 0... | |
| Where to find uni din protractor Tawa,If you want to try an alignment like UniDIN, you can use a two point protractor with similar nulls. The difference between the various alignments for a given arm basically amounts to setting up to different nulls, as explained here:http://ody... | |
| Anti-skating- test records vs. ears There is no conflict here regarding anti skate. Stringreen doesn't use it, others do. If you use no antiskate you need more vtf, and you also compromise stylus and record wear. But if you prefer that, then fine. Similarly you can always say you pr... | |
| Graham Phantom Anti-Skate. Is it effective at all? Doug:I don't expect you to defend Stringreen. I addressed you and him as you were both in the no- antiskate camp, and you had agreed with his point.You saidSkating forces put an inward bias on the stylus. The stylus wants to skate inward but is co... | |
| Graham Phantom Anti-Skate. Is it effective at all? .Stringreen, and DougA/S is included with tonearms as a selling point....when skating became the new adjustment of perfection, it was hard to sell an arm without it. In truth, A/S is very illusive...there are so many factors that contribute to it ... | |
| where to install a tonearm Hi NikolaLefthanders can always try switching the arm fingerlift to the other side of the headshell making it easier to use an arm mounted on the right hand side of the deck. (Always assuming the fingerlift is detachable).John.. | |
| where to install a tonearm In theory you can install an arm anywhere on the P2S arc and in any orientation as long as it can track the record. The manufacturer's recommended mounting distance for the 801 is 225mm. The figures 199 and 105 are just the sides of a triangle giv... | |
| Tool for measuring pivot to spindle distance? Holly, I've replied to your post on VE. You don't actually need to know the P2S distance if you can easily adjust at the base, just a two point protractor.Simply adjust the board with your protractor to set up the cartridge, like the SME. Just mou... | |
| Turntable speed accuracy Peter,Having extra flashes would not necessarily be more accurate or enable small period variations to be seen. That would depend on the indexing accuracy of the machine used to make the multi flash Timeline. A typical Rotary Head might be a facto... |
