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.

Sirspeedy, thanks for your insight, much appreciated. BTW, maintaining a tropical fish tank is no easier than what you're currently dealing with, believe me, LOL.

Frank,at one time I had a 150 gal,75 gal,50 gal,and two 20 gal "marine" set ups going,all at once!!I truly know the meaning of "pain in the tush" hobby.-:)Even had to hand feed certain species.
BTw,I still like to look at the aquarium mags,but am running out of patience,in my late middle age.Hence,the hope to just spin some damn vinyl,and forget all else.
Best.

What about the magnetic azimuth damping? Does this affect the fluid level? How critical is the fluid level when things like vta will change depending on record thickness. Personally I'm a set and forget type of listener.

Ducatirider, Do you own a Phantom tonearm?
I'm not aware of "magnetic azimuth damping". The magnaglide function has no connection with damping fluid level. Azimuth is adjustable via a moveable slide. Fluid level has nothing to do with VTA either.
