Question on FR 66s


For some reason, search on FR 66s in agon did not turn up anything much. I recalled that recommended S2P distance is 296mm rather than 295mm and Stevenson geometry seems to work best. Is this correct? I already have FR 64s which works very nicely with Koetsu. In general, does FR 66s works well with the more modern cartridges, Lyra, Air Tight, Dynavector etc.
I am kind of curious to try it but not sure what to try it with. Beside those mentioned on my system page, I have Kiseki Blue, XV-1s and Miyajima Zero on hand currently.

Thanks for any suggestion.

Dear Halcro: My first " high end " tonearm I owned was the 66, in those time my best experiences were with Denon tonearms. I sold it because I can't change directly my cartridges from one tonearm to other. I was really a rockie those times.

MY FR64 that I still own I bought it along a Luxman BD TT that still own too.

The TT-71 was really something I was not looking for but when I saw an auction the JVC tonearm that I was looking I bought it and things were that the tonearm came mounted in a TT-71 and as a " bonus " with the great JVC X-1 cartridge!. The 81-101 were not mines and heard it briefly in my system one borrowed by a friend and the other by an audio dealer.

About the Signet all the history is already in the other thread.

Please don't share the same way of thinking of those " flat head " persons , you are better than that.

In the other side I took this from Dover post:

+++ " you cannot adjust it via the headshell as Halcro suggests because you will end up with a different overhang. You must have the mounting distance correct. " +++++

normally Dover is a trusty gentleman, if the post is a wrong one then my mistake and please delete my posts, sorry for that and good to know that you really understand the whole tonearm/cartridge geometry set up.

Dear Raul, don't worry, no one was interested in a product made in Mexico (a small joke was created but all were happy when it was corrected). I am not ignorant but I am afraid that I forgot more than you will ever learn. Well, I know that you will never get it, but I am not in marketing, nor in photography nor in dealing with something :-)
Too bad for you

Halcro -
And yes......I have listened to the differences between the 230mm distance and the 231.5mm.........
However I don't think this will solve the problems you have described Suteetat?
I have plenty of 'play' distance for all headshells I have tried on both my FR arms to align for ALL the known geometries.
Halcro I may have misread your post - this implied to me that you were suggesting that the pivot to stylus distance could be accommodated via the headshell, which it obviously cant. I assume you meant to say ALL known geometries for a mounting distance of 230mm?

Thanks.
Dear Halcro: Even that you don't answer yet to the Dover post where I founded my posts there is something important to analize because what you posted:

++++ " If you use the 231.5mm S to P distance for the FR-64s.......you will not be able to interchange headshells onto the FR-66s which is best set at 295mm.
I prefer to set my FR-64s at the FR recommended 230mm S to P to match the 295mm of the FR-66s. " +++++

++++ " other cartridges ready mounted in their own headshells and all of them have been played on the FR-64s as well as the FR-66s.
In fact......with ALL my cartridges......I set them up on one of my FR-66s arms .....and then simply swap them between 4 of my other arms " ++++

So, you just swap in between with out modifications, right?

How can be ? which kind of geometry equations or manipulations you do for you can make that because that's what I need and maybe other persons too. Yes, I'm willing to learn as always.

Your answer is appreciated, please enlight us. Thank's in advance.

I have to say that back when Halcro asked about setting up his cartridges in separate headshells so that each cartridge could be used with each of his tonearms (at the time, I thought he wanted flexibility among several tonearms, not just 64S and 66S), I was dubious that this could be done without at least some minor re-alignment each time. (And we know there is no such thing as "minor" realignment; each time one must do it, it is a pain in the arse.) Later, when Halcro claimed he had conquered the problem, and since he was pleased with the results, I assumed that perhaps I had been wrong and /or that Halcro may have found some compromise that is "good enough". Now that the issue appears to have been put before us again, I am interested.

Right now, the question seems to be that if you mount the 64S at 230mm and the 66S at 295mm (factory recommended, as I understand it), then a headshell bearing a cartridge that is correctly aligned for use on the 64S will also give perfect alignment when that headshell/cartridge is transferred to the 66S. It would seem that someone who has actually done this using a quality protractor to evaluate alignment on both tonearms could tell us the answer. Also, Euclid could tell us, if he knew the other relevant parameters.
