Graham Phantom with Benz Lp-s Tracking problems


Hello to all,

i recently mounted my new Lp-s cartrige on the Phantom B-44. The sound is great, but i have problems with some Lps, 4-5. On all it is on the beginning of the record. I can see a little but quick jumping from the cartridge, it isn´t much but the stylus looses contact with the groove and i hear something like a rumble. I don´t know if it´s the right word. And when i put up the volume it distorts. Benz told me that the best way for working the Lp-s is that the counterweight should be very close to the center of the tonearm and it isn´t, it is 1cm or more away from the top.
I wrote Bob Graham to tell me his thoughts, will see what he tells me. Maybe i have to change the ring of the counterweight to a heavier one!?
Has someone experience with this problem?

Many thanks and happy new year !!!!!!!!!!!

Best wishes from spain,

Add some blu tak to the Phantom on top of the headshell. Basically increase the mass of the cartridge. This will move the. Counterweight distance from the pivot but you can add mass to the counterweight as well to bring it closer. This will reduce the vertical resonance which should be your problem. 18hz is way too high.
When I bought my Aries 3 w/Benz LP-S cartridge my dealer called VPI and told them I was getting a heavy cartridge - 16 gms. Harry Weisfeld put a different counterweight on the arm than the stock factory weight. I can't say that's your problem, but I would ask Mr. Graham if that is a possibility. That being said, you should make sure your tracking force is at or 0.1gms above max recommended. Good luck.
I've got a phantom 2 with lp-s and it tracks beautifully. I hope you resolve your issues and get to the point where you can realize and enjoy the incredible potential of the combination.
Carl, as a Phantom II user myself, I'm interested. What's different about your combination? Is it unmodified or did you get the heavier counterweight?
