Mounting Graham B44 arm on SME 20/2
I acquired a Graham Phantom II B44 tonearm having a standard (circular) mounting base with the intention to mount it on a SME 20/2 platform. The previous owner had the arm mounted on a SME 30, using a custom base adapter (sub-base). This circular custom base replaces the base on the SME plinth that provides the slotted hole for SME tonearms, and provides a center hole plus additional mounting holes for the standard Graham tonearm base.
Sadly, this custom sub-base adapter was shipped via FEDEX separately from the arm, and was lost by FEDEX!
So far, all my searches have not given any fruit in locating such a custom adapter. I am still pursuing it but I am posting here in case the group can offer any helpful ideas in sourcing such an item.
I have read that the B44 can be used with a variety of turntables using custom mounting bases. So far, I have no idea who sells such bases. To avoid confusion, there is a version of the Phantom II/III that comes with a mount to fit the slotted SME base. That's not the version I have.
Also, after contacting SME directly, they don't provide any other bases.
Thanks

This is the current mount on the tonearm This is the mount I need https://media.graham-engineering.com/wp-content/uploads/2025/11/graham_phantom_iii_0.jpg |
This is not a hard problem. Option 1 Send the arm to Graham and get them to swap the base to an SME mount. That's the easy solution. Option 2 Put the existing mount on your current SME mounting plate, set the pivot to stylus position, and then mark up the screw holes required to mount the arm in the correct position. You should be able to get at least 2 screw holes either side of the SME "slot" to bolt the arm down. Then get an engineer to drill and tap the screw holes. Because the non SME mount has quite a large footprint the arm will be quite stable with 2 screws - 1 each side of the slot. The only downside of the option is it is not pretty, parts of the SME "slot" will still be visible. I could drill and tap the holes required in 5 minutes - its a simple job. If you want to do a DIY you could drill right through and use long machine screws and nuts - then you would not have to tap the holes for the screws if that is beyond you. Option 3 Position the arm on the SME base, with the correct pivot to spindle, mark up the screw holes and hole required to the arm pillar, remove the base and take it to an engineer to CNC you a new base. If all of this is too hard for you, then send it to Graham ( option 1 ) or sell the arm and buy an arm with an SME mount. |
