Fidelity Research FR-7 Repair

I thought it was Stevenson for this?

The original alignment is Stevenson, if you want a protractor with all 3 alignment method and precise ruler for PS distance for any tonearm/cartridge then buy Dr.Feickert.

Mint will be made for 1 tonearm and 1 cartridge only. 

With headshell integrated cartridge like FR7 series i would advice for you to stick to the manufacturers method, do not change the length of the cantilever. 

You could actually order aluminum cantilever with the best possible stylus profile like Gyger.

It's a massive cartridge and even of the Boron is the strongest it can be destroyed (bent) just like any other cantilever :))   

I will hopefully mount this thing and never mess with it again, well you know what I mean. So the Mint sounds good to me. I like the idea of: "If Stevenson was good enough for Mr. Ikeda then it's good enough for me." I don't see changing this ever again. The only thing I can see happening is someday buying the FR-7fz.

I gave Soundsmith the go ahead for boron/CL earlier today so that part is in process. Now, I need to figure out what skills I need to learn how to put the thing on. That other headshell thread had my head spinning....

Well, actually all you need is to measure Pivot to Spindle distance which you CAN’T DO with mint protractor. If you PS is correct according to Mr.Ikeda (read the manual) your stylus will be spot on (Stevenson). But if the length of the cantilever will be different after refurbishing then it will be off! Remember that you can’t twist this cartridge/cantilever to the left or to the right for use alternative alignment (with alternative alignment cartridge must be slightly twisted ion the shell), if your refurbished cantilever is longer or shorter you will have to mess around with position of the amr hole and PS distance (this is far more complicated).

 I like the idea of: "If Stevenson was good enough for Mr. Ikeda then it's good enough for me."

Definitely, that's why i use manufacturer recommendation (Stevenson alignment) for my FR-7fz 

''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.
