Graham Phantom damping fluid level.

Bob Graham says to use enough fluid to bring the level up to the top of the square profile machined on the bearing cap. The square is only about 1/4" in length. My question is, What level works best for you in relationship to this "square" profile?

I have tried only 3 different levels of fluid in my setup (maximum level to top of square, almost no fluid at all, & to the bottom of the square) but can't seem to obtain optimum results so I'm wondering what others use, although I guess it's really cartridge dependent. Is the fluid level super sensitive? FWIW I'm using a Koetsu RSP.

It's wonderful... I'm playing with VTA now... I'm finding that tail up is producing much better results for me than level or tail down. This is the exact opposite of any other cartridge I've ever owned.

Various searches that I've done are confirming this as well. Have you experienced the same with yours?

Bofh,with tail up too much I don't like the tonal quality I get.Down gives me a slightly deadened sound.I am "about" parallel to the LP(cartridge body),with an itty bitty tail up position.BTW,the azimuth is "incredibly" important with this cartridge.Absolutely SPOT on is mandatory!!Remember,my cartridge is not close to being broken in,so things will change....An amazing little device though!!

Sirspeedy, speaking of azimuth....how do you verify "spot on" azimuth? BTW, I've been living with the fluid level just above the start of the squared off shank myself and it is much better.
Now if azimuth could be set accurately without the use of meters and test records, etc. I'd be ecstatic. What's your secret method? LOL..

Frank,no secret method!I was loaned a Wallytractor,which looks to be supremely good at this,BUT what I do personally,is use my own set of reference LP's which I know "extremely well"!!This trumps any device,for me.I started out assuming the Wally would be required,but wound up using my ears,and my own set of set-up LP's!
Best.

Just got my Phantom mounted. I'm assuming you're using Magneglide at 3 ticks.
