will do, thanks.

A quite spectacular mod, a total rework, it looks very impressive from the rear.



There is a great read on the site, but here is the point I ask to Domonic which you find of interest about the arm mods and the holes in it.

Polishing an arm tube
Unless you intend to carry out other mods to the arm tube, removing the paint will
make it sound far worse than standard.
There is no sonic advantage in polishing the arm tube. It looks nice.
There are advantages in bead-blasting the arm tube Michell style, because that affects
the surface hardness a little. It also makes good commercial sense for them, because
it’s quick and hides surface imperfections.
Drilling an arm tube
This does have sonic advantages. The pattern and number of holes isn’t critical, but
there are mechanical and sonic advantages in the spiral drilling with graduated hole
sizes that we’ve developed. The exact layout and size depends on the target mass and
the range of cartridge compliance aimed for. Michell and Origin Live now drill/slot
their armtubes. We started in 2003. Enough said.
You could choose either spirals or a row of holes underneath (Michell) style.
Spiral holes have the advantage of reducing mass if that’s needed for a highcompliance
cartridge.
Slots: I have reservations about slotting the arm tube, though I have no test or
experimental data to support it. The strong point of the Rega arm tube design is that it
is deliberately very rigid. It would be expected that reducing the rigidity by cutting a
long slot would tend to introduce bending vibration modes. Maybe this is OK, like
second harmonics in a unipivot.
Earthing the arm tube
The arm is originally earthed by a strap fixed into the counterweight thread. This can
cause problems even on standard arms.
If you are using our upgrade kit then the armtube must be earthed – ceramic bearings
won’t conduct!
Our method is to drill the armtube to add a very small copper stud onto which the
earth wire can be soldered. This is kept completely separate from the signal wiring
and taken direct to ground.

How much does all that work add to the price?

Hi Greg, the arm can be purchased either as a kit with no arm tube mods, or as a kit with arm tube modded, or as a complete arm as shown above.
Plus I can bead blast the arm components if needed for an additional fee, and or wire the arm with my own solid core pure silver rather than the silver litz used as standard.
