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.

Mine was manufactured in 2006 s/n 3137 so that is why it came with the spacer. I prefer the sound with the spacer installed.

Hey guys,
Hevac1 {Leo} here.
I purchased a Phantom and recieved it 3-10-08 after 2 years with a 2.2 and it is sounding awsome. I have the fluid just after the square section but I am bottoming out on the VTA and still need more room. I do not remember getting those spacers talked about here with either of my wands. I have a Koetsu Urushi and a Lyra Helikon Mono.
I tried to call Bob Graham and have had no reply either. The last time I had spoken with him he was having some big health issues with the family so it will take a while for him to get back to us. Keep leaving messages though so he will remember to call you, he has a lot on his plate so to speak at this time. I live 5 minute from his office so as his problems clears up I am going to see if he could make a house call. Fingers crossed.

My whole point is that you can't leave a message. His voicebox is full. BTW my serial number is 3280. I can't imagine the isues one would have with a low profile cartridge like a 17D3. That thing is very squat.
