It was Ortofon's short vs. long headshells for SPU Type A vs. G (respectively) that started the different top vs bottom pins thing (with Type A having a bottom pin only, and G a top pin only). Basically, there were variants of Ortofon tonearms for A vs. G headshells with the slots being either top or bottom and therefore only accommodating one or the other cartridge/headshell assembly. When SME designed the original 3009 with sliding base adjustment they put slots both top and bottom within the headshell socket such that either Ortofon SPU A or B could be accommodated.All original SME-supplied headshells have one pin to my knowledge. I think the bottom one is for compatibility with some other earlier shells from other brands. My SPU knowledge is not great at all, maybe some very early ones had a bottom pin, or two pins?
Early SME S.2 headshell with two pins:
Right you are, Tony, that headshell is S2-R.Really good post, but I’m certain that is not an early SME headshell, from the side it looks like the one from the M2R range (see fingerlift screw), though I’ve never seen one to confirm it has two pins. I’m pretty sure the solid headshell in my first post of this thread is the earliest SME-made shell (i.e. not a rebadged Ortofon). It only has a top pin.
The two pin design addresses an obvious flaw to my mind, I wish they had adopted it. There is just enough ‘slop’ in the headshell mount on any SME that if you look carefully you’ll note the shell is pushed very slightly up at the front by the strong spring force of the pins. It very slightly impacts VTA etc. I assume two pins would make for a marginally more solid and better mated joint too. A missed opportunity.
PS Edit: that is definitely a M2R headshell!
Suggest having a look at the end stub, as this appears to be sans original coupling rubber.
Is there a way to judge the age of a 3009 II?
I did notice the acorn nuts condition, but didn't want to come across as being too negative wrt what is a wonderful find. After all, considering the age of these, finding one that likely only needs a couple of fasteners and rubber grommets replacing in order to appear as new is almost a miracle. Your patience has obviously paid off.I think that is right. Certainly looks very similar to my current split-weight. As ever with SME there are countless changes between versions.
After scrutinising the pictures the only thing I can see I’d want to change are the baseplate acorn nuts where someone has taken a screwdriver to them (just don’t!). I’ll just swap those with mint ones.
Were I were holding onto my existing arm anyway, it wouldn't trigger my OCD too much to swap end stubs and counterweights between them, should an arm tube prove not to be fully up to scratch(less), for example. Certainly beats swapping tubes between two SME arms (speaking from experience here).I’m more than a little nervous as even pictures that good can hide things, e.g. I’d have liked to see the armtube under the arm-rest to see if it had scratches (the 3009 on my deck is perfect in this regard, in fact it could pass as new), plus I’d very much like to have seen the packaging, manual, cable and extra weight, as I’m certainly factoring these heavily into the value. It certainly looks good, and acorn nuts are no issue, I stuck NOS ones on my current arm and the S2 Improved I have boxed-up, so I’ll just swap stuff around a bit. I want to keep my existing arm exactly as-is (it is boxed, with manual etc), I’ll hold onto that regardless, though the other split-weight (minus headshell) and boxed fixed-shell S2 Improved may find their way onto the market. I have sold a couple recently, a beautiful one exactly like the one on my deck, and a very early Improved, so I’m not entirely hoarding the things!
A job I’ve not done to a SME as I couldn’t work out how to get the cover off!
This is something I may yet need to do on all three of mine (well, five if we count immediate family) - but have been putting it off. There is no good instruction video that I have found, or even a pictorial - so I may have to resort in making one, even if I cause damage on one of them.
I’m suspecting it involves desoldering the arm-base, removing the whole lift-lower/armrest assembly, removing the little rubber pad that may get damaged, and then taking a heat gun to it or heating the whole thing up in hot water. The cover is obviously glued on somehow, so that will need softening. It has to be possible, and possible without leaving even the slightest hint it has been done. I’ve not owned one that can just be slid off in place, and I’d obviously not take any tools to it.
