letch, What do you mean with 'wacked in a move?'' Bent aluminum cantilevers can be straitened. But if the stylus is wear off you can retip your cart with boron cantilever + whatever stylus you chose for about $ 500.

letch, The problem with Russian people is their ''soul''. So sensitive that they always complain. Our chakster is complaining about the prices of new cartridges but owns an collection which must be in contradiction with his ''income''. Curious expression if one has no job. As paradoxical is his advise to buy ''an perfect FR-7fz'' instead of fixing your ''common'' FR-7 . He wisely deed not mention possible price for ''FZ'' but also ''forget'' to mention where such ''perfect animal '' can be find. You should listen to his older brother who knows better. FR-7 is excellent cart and certainly deserves retip.
|
letch, ''They said my cartridge survived the damage but needed repalcement''. This make no sense. Not the cartridge but the cantilever/stylus combo needs replacement. They suggested the most expanisive alternative. Deed they mentioned the price? My estimation was +/- $500 for boron + stylus. This can be done by any retipper. Boron cantilevers with styli are produced by two Japanese companies. Both manufcturers and retippers are provided by the same companies. In some sense you will get a new FR-7. Anyway no worry about stylus condition.

Hi letch, By Yip from Mint tractor you need to provide him with exact dimension of the spindle of your TT (those differ in thickness) as well which geometry you want. He can than make an special tractor for you. If you chose for Bearwald geometry you should also ask Soundsmith to increse the length of the cantilever suitable for Bearwald. |
It may look as if I have something against my younger brother or to enjoy teasing him. But the ''truth'' is our religion which must be obey. Now the case is that not all FR-7 kinds have the same cantilever length. Ikeda obviously experimented with different cantilever length . This btw may explain his (later) cantileverless designs. So the worry about the''right geometry'' is , say, questionable. As we can see(?) the other advantage of aluminum (alloy) cantilevers next to ''pressure fitting'' instead of gluing the stylus IN is that it can be straighten if dent for whatever reasons. Try this with the so called ''exotic kinds'' and you will discover what this advantage means. The curious thing is that while my brother recommend ''exotic kinds'' and long for beryllium and hole boron pipes he admire the most his Takeda cart with aluminum cantilever. The only risk our letch may be confronted with is refusal to to straighten his cantilever because no profit can be made by such ''repair''.

''Pure theoretic'' consideration means without any experiment or experience. This is identical with ''assumptions only'' aproach. So the only possible check is logical: if the assumptions are not true then neither are deduced statement. Our chakster believes in manufacturer authority and intentions despite our long disputes about tonearm geometry. In addition he distrust retippers and never retipped any of his carts. So his advice is ''based'' on his believes. Letch could also ask his mother for advice. The difference between Stevenson and Beearwald is about 1mm. Aka effective length Stevenson 245 mm, Bearwald 246mm. I can't remember how many retips I have had. With Axel my retipper for years I become friends. Alas he was/is not able to do the work because he lost comand of his left hand. But he was nearly 70 and with 50 years of experience.

Again assumptions. They probably will but this would imply Stevenson geometry. My FR-7 fz sample .is retipped by Van den Hul who increased the cantilever length to fit Bearwald geometry. So I got boron cantilever with Van den Hul (aka Gyger) stylus. My Mint tractor is made for my SP-10,mk 2 and Bearwald for my FR-64 S. I owned all other FR-7 kinds but kept the FR-7 fz. The only technical difference is (slightly) higher output by FZ. I am sure you will be satisfy with your FR-7 . Also the price at $450 is modest in comparison with European prices.

Dear chakster, Our ''dispute'' become very difficult if one confuse spindle to pivor distance with effective lenght and persist in believe that manufacturer ''know better''. As Raul and Kessler& Pisha have shown neither of all 22 tonearms are without errors. Primary by ofsfset angle and overhang. Either they considered tonearm geometry as not important or were not familar with them. You also suggest that retippers use different cantilever/styli combo's than manufacturer. But both get those from the same supplier. If you assume some special art needed to glue an new cantilever in the joint pipe you probably have never looked at those parts in an MC cart. Each retipper prefer to do the whole cantielver/stylus instead of stylus only retip. No wonder by the price difference ;$ 200 versus $500. Axel refused even to me to do stylus only retip. He got so much work that he was able to chose. I then moved to Expert stylus in UK who still do stylus only retip for 200 euro. They also produce styli which are identical qua dimensions with Van den Hul. They provide Deccas with those styli. . |
Dear chaksrer, you are again back to parts. Lets talk about them. The coils are the most difficult to repair. Nobody wants to mess with those. Then there are dampers. No retipper has the ''original'' but, say, 3 unknown kinds meant for different compliance. The most easy job is to supstitute cantilever/stylus combo. Stylus only retip is much more difficult to do then cantilevr/stylus combo. But the most people are arguing about this part. So the ''most people'' have no idea what they are talking about. Think about LP 12. What are original and what improved parts? Who can ''compose'' one LP 12 from ''orignal parts'' or, to put this otherwise, what are originl parts by an LP 12?

''ít will not sound the same when you change tip or cantilever''. But this may also mean that ''it'' can sound better. To grasp the issue one need to see how any cantilever/stylus combo is glued into ''joint pipe''. Joint pipe is usually an aluminum pipe on which coils and tension wire are fastened. In this pipe all manufacturer and retipper must put the same cantilever/styli combo as provided by big (Japanese) supplier. Why the manufacturer are assumed to do this job better is an enigma. By such circumstances one should check his premiss and start again if the premiss is not true. The used glue needed to ,uh, glue the cantilever in the joint pipe can be desolved in order to remove old and substitute the new cantilever. The retipper need to use the same length and stylus orientation. That is all. |
Dear chakster, You changed the question . The question was or assumed to be about sound not styli variations. Whatever the stylus shape or cantiever material they all need to be glued or fastened into cantilevers and glued into yoint pipe. As you I also admire Takeda's Miyabi and Ikeda's FR-7fz. Both with aluminum (alloy) cantilevers.
|
Letch mentioned to own FR-64 . If so then he owns FR-64 with aluminum wands . The lateral balance is also different from 64S. Anyway if the spindle to pivot distance is right he can fasten his FR-7 direct to the arm without any tractor. After all he has chosen Stevenson geometry. |
letch, you can use your FR-7 as model for all other headshell/carts combintaitons. But you need an PLASTIC caliper for this purpose. You measure the stylus distance in your FR-7 (integratded) headshell and use this distance by other combos (aka adjusting the effective length). Reg. your Orsonic. I hope you own the AV-101 ; the other are mediocre because the lack of rigidity (AV-1 and AV-11). |
"The protractor'', ''an protractor'''or ''whatever protractor''? The tonearms lengths are 9'', 10'' and 12''. They ''assume'' different effective length. Aka the stylus distance to the pivot. Letch owns 10'' tonearm (FR-64) while eff. length is 245 mm for Stevenson and 246 mm for Bearwald. If his FR-7 got the cantilever with the same length as the original this length can be used for whatever other carts and headshells. Assuming the headshell has slots allowing movement of stylus in both directions. My guess for the cost of an plastic caliper is $10. |
Sorry chak, I see an rubber ring behind the headshell connector while the higth of this ,uh, cheap instrument, does not allow lowering of the stylus to the marked position. One need to guess where the stylus point should be. Together they make at least 2 mm error. So there is then no sense to speak about different geometries. But if one use (plastic) caliper with one ''leg'' after the connector (without rubber ring) and the other on the stylus point one will get exact effective lenght and use the obtained lenght for all other cart/headshell combos. I adjusted this way 20 of my MC carts in their (separate) headshells . Checking with my Mint tractor made for my SP10 /FR-64 S (Bearwald) confirmed the results. Changing carts can then be done in 5 minutes time. |
So dear chakster, You can sell your Feickert and buy one plastic caliper which you can use for all your carts/headshell combinaions. The only thing you need to separte are your tonearms and headshlls which you use with them. |
Try google for ''plastic caliper''. Those are even cheaper than I thougth. |
Dear lech, your ''info'' is confusing: ''all the carts which I used with Orsonic'' clearly suggest more than one cart. Well you don't need the caliper for only one cart (FR-7). Caliper is for ''copy'' of one good adjusted cart. The eff. lenght (distance pivot -stylus tip) can be repeated by other carts. |
Dear chakster, the sense of caliper is to use it as ''marked distance'' of the stylus in its headschell . This assumes many cartridges and headshells so by changing carts and headshells one need not to use his tractor but the caliper instead. Much faster and much less boring then aiming the stylus on the tractor lines or points. You can then keep pre-adjusted headshells for respective tonearms ''ready to use''. I have 20 pre-adjsusted headshells for my FR-64 S. So I can change those carts in 5 minutes time |
