Question on FR 66s

Speaking about repetition. This is 33 1/2 time we dwell about tonearm geometry. The 1/2 one was the thread with only two contributions so it would be not correct to count
this one as a whole thread. I play my records only around the O points with the least possible distortion. Even Raul with his distortions obsession never got this idea. However his 'learning curve' still make some progress... Depending from the part of the record which one want to hear and enjoy in the most pure way one should of course use the geometry intended for this part.
I am however not sure if all 45 preadjusted headshells in Australia can be used in both tonearms (66 and 64) this way. Anyway it is impossible to use one half one way and
the other the other way. So the dilemma in this case is in which to use 23 headshells.

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.
