Only precision ground theads in high quality carbon steel really qualify for acceptance from a sonics point of view. and these are not to be found on the ends of Jelco or even SME arms to my knowledge.

Mike, I'm aware that fixed headshell is sonically better, but I'll still prefer the removable solution. So the Q is: will your 12'' extension deal with tonearms like Jelco ?
Thank you

Yes it will but of course the attachment arrangement will differ from the SME
What is the spindle to pivot distance for the Jelco??

EDIT: Mike, please give me/us an idea of the final cost, too, thank you.

You must have that saved as a template judging by the regularity it comes trotting out.... you should apply for a job as a traffic warden! :lol:

Gdg,
The cost of the 12" adapter will be about Stg165. plus postage for the Jelco mounting. The cost of engineering grade Alluminium contributes to this price, as the top mounting plate which fits into the existing arm well is machined from a 25mm thick by 120mm wide bar, as is the arm mounting plate. I would need to specifically make a version for each of the differing arm mounting geometries, The SME being the more involved, as it requires an elongated 28mm slot for adjustment, although it will not require to be as long as the standard mounting template indicates, as cartridges just do not vary in length by that amount! do they?

Hi guys,

AOS has a great analog forum!

I had requested Vantage audio to make me a mount to fit a 12" Jelco on the back left of the deck. I hope he can accommodate my request so I can keep my SME 309 and add the SA-750L. Wouldn't this be a better option than retrofitting a 12" in place of a 9"?
