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.

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.
Hello Ducatirider,
I talked directly with Bob Graham yesterday, (he actually answered the phone) so give it another try. He was on his way to the doctor office so could only talk for a few minutes.
I asked him about the spacers every one is talking about here and he said it really didn't matter if you use it or not other than it is being used with lighter cartridges.

My post about my problem is wrong on my last reply. I am having an issue with anti-skating and not VTA. I use the Denon test record for setting anti-skating. On track 10, about center of the record the track starts to distort on the left speaker before the right speaker. I make adjustments to the anti-skating, but have found that I am at the end or furthest away. The distortion is still off to the left but I cannot make it correct. The noise should come from both speakers at the same time. Bob suggested I increase my tracking weight. The Koetsu settings are 1.8 to 2.0 and I am at 1.95.
WhatÂ’s bothering me is Bob said I can go up to 3 to 3.4 grams. I am very nervous about setting a $4500.00 cartridge at a higher tracking force than recommended by the manufacturer. I could break the cantilever and be shit out of luck.
Any help on this matter would be appreciated.
I did not have this problem with the 2.2.

Thanks.
Hevac,some test records(I own the Telarc Omni-disc)may not allow for the distortion to "totally" go away.I know my Phantom,using my Omni-disc still exhibits a certain degree of distortion in one channel.I believe we want to shoot for least amount heard,if it cannot be totally eliminated.
What I do,is get familiar with the actual "volume" of the distortion,as well as how long the distortion lasts,timewise.I play the track over,quite a bit,to become familiar.
I voice my arm for lowest volume,and shortest duration of this distortion,but one can always go from "that" point using one's ear,as well as watching the cantilever trace a groove,when viewed from straight ahead(front of cartridge/arm).It should be as vertical as possible,from a frontal view,as a disc spins.
Good luck.
