The old (Shure) cartridge I use has two clear holes for fixing it into the
headshell of the arm. The actual headshell has one clear hole. So I also have an adaptor plate which has tapped holes. (Or nuts in captive slots. Can't recall which, and they are hidden in use!) I have been looking at modern cartridges and noticed that it is common for them to have blind tapped holes for fixing purposes. So, do cartridge manufacturers now routinely supply adaptors for headshells and arms that *don't* have two clear holes/slots?

One is the Mission 774, another is the EMT929 . The Audio Technica headshell as supplied with the AT33 cartridge and AT1010 arm had fixed tapped holes, but as the arm had a standard SME mount, any headshell could be used. I'm sure there must be more, but can't think of any at the moment. Anyhow, there can't be that many, and I suppose cartridge manufacturers go for the mainstream, which means tapped holes in the cartridge are OK. Personally I don't like them, as I have to drill the holes out to fit my EMT (as I had to do with an otherwise wonderful Sumiko Talisman B) or try and find screws of the right length and the right threads. (why can't everybody use metric threads.....) S. -- http://audiopages.googlepages.com |

Wonder if that would fit the Technics... Problem, of course, is that if I wanted to change to anything other than a Shure I might end up having to also change the arm and TT simply to be able to fit in a new cartridge. That would be crazy, so some sort of adaptor plate would make more sense. Hence my wondering what cartridge manufactuers supply. I do have a variety of spacers, nuts and bolts, and adaptors, but all from 20+ years ago. So no idea what anyone supplies nowdays.

The original arm tubes for the early Mission 774 were like that. Later when cartridges came out that had tapped threads in them (Dynavector Ruby & Diamond may have been the first) they made an arm tube that allowed fixing bolts to be inserted from the top down into the cartridge body. I know, I still have both. |

As you seem to have an HND I assume you know the difference between 'clear' and 'tapped' holes. :-) The critical point is that old cartridges (like the Shures) used clear holes (or slots) in the body, but current designs seem to use tapped holes in the body. The system I use caters for the Shures, not the cartridges with tapped (generally blind) holes. Hence my asking if cartridge makers supply adaptor plates. Although it looks like people have forgotten that there has been more than one 'standard'...

Aha! Thanks, that is excellent info. :-)) Where can I get them? I can try buying one or two, and then experiment. Well, saw my legs off and call me Shorty! I've just looked in my CPC catalogue and they list two different headshells. These look very much like the 'technics' type. I suppose these have become common as a result of the technics turntables becoming established for 'DJ' uses. I'll order a couple and see what they are like, unless someone can suggest another supplier who might be better for some reason! FWIW I also have an old GL75 headshell which looks similar, but I thought was slightly different in collar diameter, etc. But I'll bring it home and compare. Actually, it occurs to me that the GL75 has a straight arm and the connector is angled wrt the cartridge, so presumably not compatable.

Also, the headshell is so heavy that you wouldn't want to put a V15III in it even if it did fit. I have several "universal" headshells which fit all arms with an SME-type mount (it does apparantly have an IEC number). One peculiarlity of SME's own headshells is that they have fixed cartridge mounting holes and you slide the whole arm back and forth to align the cartridge, whereas everybody else has a fixed arm and slots on the headshell.
