FR64 to FR66 conversion Analogmagik


Hi guys

 

I read the thread started by @syntax whose opinion I genuinely value. I have decided to get Richard Mak to refurb my FR64s arm.

 

Whilst on the website I saw you could get an FR66 replica arm tube.

 

Has anyone done this conversion?

What is the benefit of going 9 to 12 inches?

There is a very solid school of thought advocated by the maker of the SAT arm and the late great Max Townshend that the shorter the arm the better - rigidity and also resonance outweigh tracking improvement…

 

I would be grateful for the input of anyone particularly those who have both arms or got the conversion 

 

thanks 🙏

If you live near enough to Bethesda, you are welcome to visit in person.

Also check out Halcro’s plinth for his TT101, photos to be found in his long thread where we argued about outboard tonearm pods. Key word for reference is “Copernicus”.

I can only fairly say that to my ears the stiffened OEM plinth plus the mass-loaded mounting board plus the FR B60 base for the FR64S sounds “bigger” and with superior bass response compared to the original configuration. I could send photos if your interested but not until next week as we’re vacationing in northern CA at the moment, and  I live in MD.

FYI, I use my FR64S on my modified QL10. Plinth has been heavily reinforced with aluminum and the armboard went in the trash in favor of an aluminum copy that is also bulked up. At that point in my audio life when I acquired the QL10 and fixed the TT101, I had no more patience for creating a new plinth from scratch. So I improved upon the original.

If 9 inches isn’t enough…

I’m just saying.

Seriously, although the FR66S commands much bigger bucks than the FR64S, from a collector point of view, I’m not sure it’s a good idea to convert one to the other, especially given the probable high cost of the conversion. It’s really a matter of personal choice and having a cartridge that’s particularly suited to the even higher effective mass of the 12 incher. I do know that some of our European friends revere the 66.
