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?

Slainte,

Jim

Gosh, that's an early Garrard SP25 you have there Jim! (OK, just a
guess). I can't say I have heard of any recent head shells without the
standard pair of holes.

Offhand, I know of only a few arms that don't have standard holes or 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.....)

Technics SL1200 of early 1980s vintage. Works very well with the Shure
V15/III. :-)

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.

Slainte,

Jim

The screws go down through the headshell into the cartridge.`
I would have thought that was obvious!

I've just looked at my Mission 774 arm (on an old Dunlop Systemdek) and it
has tapped holes in it so the screws go up from underneath.
I don't play LPs very much, I'm afraid.

Yes, but what if you don't have a headshell. Your 774 for example.

Elastic band or Sellotape will do for that.

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.

ahem Can I directed you back to what I actually wrote? 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'...

Slainte,

Jim
