Graham Phantom mk II & JA Michelle ORBE se help


I purchased a new Phantom with SME mounting for my ORBE se. According to Bob Graham's ad slick, its a drop in replacement. Not so. The geometry doesn't work. Using the orbe tone arm board cut for a sme mount, the set up is not acceptable. Then when playing a lp, the counterweight hits the vta column and the last groove will not play to the end. It's also not possible to use Graham's set up procedure due to the position of the arm relative to the spindle. JA Michelle doesn't have a new armboard for a Graham with SME footprint. Only the new Graham mounting. Not to mention the extra weight. This is very frustrating. Any easy solutions other than to recut the arm board, and try to shave some weight off of it. Had I ordered the Graham with the Graham mount, and purchased a new arm board, all would be ok, but again, the ad slick said it was a drop in replacement.

I had a similar situation when upgrading from the Graham 2.2 to the Graham Phantom using the Graham mount. Like your case, the counter weight hit the VTA post when trying to set the arm to spindle distance. I backed off the counter weight to avoid the post and get this distance set correctly. However, unlike you, I am still able to play all of the groves with the counter weight reset for proper VTF. I still plan to redrill the arm board at some point to get the arm properly oriented.

I am posting this to alert others contemplating a Phantom upgrade, that this situation can occur with the Graham mount as well. Do not let this disuade you from the purchase, just be aware.
