Do you mean the diameter of the arm pillar, or of the hole required in the armboard for the collar? The answers are 18mm and 30mm respectively.Quote:

Does that cover what you wanted?
I now have a new batch of collars ready. The main change is that they are now available in black, silver, or grey finishes:

The grey finish is a nice match for the grey SA-750 tonearms:

The cost has had to go up, reflecting the postal price increases that came into effect on 1 Apr (April Fool's Day?). Prices, including insured postage, are now £45 for the UK, £47 for Europe and £48 for the rest of the World.
The collars will also be available from David Brook at MCRU.
Thanks Hugo
I didnt make myself clear sorry looking at your collar I need the internal hole size which is probably a few thou larger than the arm mounting tube ?.
Lovely pictures by the way
Alan

You get extensive fitting instructions and bolts, nuts, spring washers, allen key and small nylon arm pillar protector which I think is a nice option.
I can't wait to fit it..........
........all I need now is a 750 to fit to it:doh:
Hugo, hope you don't mind me doing this, cheers and many thanks.

Hi Shuggie,
I am doing some upgrades on my Thorens TD 320 TT (new Lyra Delos PU in place and a Oyaide tonearm cable on it's way) and wonder if should get one of your collars instead of the original, which is kind of "wobbly".
Do you think it will fit on my TT and is it easy to replace the old one?

BTW, my tonearm is AudioQuest PT-6 (Jelco SA-250ST), not SA 750. Will the collar still fit?
Regards,
Dag

Yes, the collar will fit, since the Audioquest has the same 18mm diameter pillar as most Jelcos.
Anyway, you will definitely benefit from a better mounting collar, but you may have to get a new armboard; or at least modify the existing one, since the collar fixings are clearly different, but you might be lucky and find that the opening for the PT-6 collar is the same as for a Jelco. A new armboard would probably be the easier option, particularly if you are handy with metalwork .
My collar is exactly the same for fitting as a Jelco original, so you would only need to get (or make) an Jelco-compatible armboard with the correct size hole, placed to ensure the correct spindle-pivot distance (211mm for a the PT-6). You can download a Jelco mounting template from Vinyl Engine (go to the Tonearm Database). So, apart from potentially modifying or replacing the armboard, yes it is easy; and handling/adjusting the tonearm would be much easier with a decent collar. The nylon stub provided with my collars will also prevent the grub screw damage that can be seen in your photo
I do have just a few of the B-Stock black collars left, priced at £28 + £10 postage to Norway. You can have one of those straight away, or wait for the new (even more improved) version of the collar which will be available in grey. The new ones will be more expensive and I can't yet tell you when they will be available.
I hope that helps
Hugo
