Question on FR 66s

Raul, North of your border, a spoiled female would say, "Peel me a grape". There's a great jazz tune with that title, written by Dave Frischberg.

If one is going to use a protractor, is it a bad idea to use a "good" one? I think not. I did not use the word "expensive"; I used "good".

Suteetat,
In re-setting the FR-64s at a P to S distance of 231.5mm.......I discovered one cartridge/headshell combination which locates the screws at the furthest point of the headshell.
The Signet TK-7SU in the Yamamoto HS-1As wood shell is the only combination exhibiting this structure.
At this furthest point......it has perfect 'Dertonarm' geometry :-)

By the way, good luck with getting the overhang accuracy to 0.3mm, so as to distinguish between 14.7mm and 15mm, anyone. A little cantilever flexing will obliterate any such precision.

Halcro, thanks for your information. I mounted XV-1s yesterday and there was a few more mms wiggle room than Air Tight using Baerwald geometry on Feickert protractor.
So look like it was Air Tight and not something wrong with my arm or protractor as far as I could tell.

Feickert protractor is rather difficult to see especially if I have a light source on the side or the rear to help me see better. Light source is very useful for Air Tight and Koetsu especially but not as needful for Dynavector or Lyra. Surprisingly, I get a lot of glare of the black surface. Clearaudio silver finished is easier to see but Mint mirror surface is by far the best.

I saw Uni-tractor on acoustical system website. Is that the same protractor that Dertoarm made awhile back? There is an economical version call SMARTrack. Looks interesting!

Dear Lewm: ++++ " is it a bad idea to use a "good" one? I think not. " ++++

agree. As a fact there are not bad really bad comercial protractors.

Regards and enjoy the music,
