Eminent Technology ET-2 Tonearm Owners

Frogman - I used a cupboard door magnet. It had a pair of magnetic plates implanted edge on. You see 2 parallel edges exposed in a plastic case. I placed these on the plinth, under the bearing tube with the edges in line with the bearing tube, next to the manifold, on the other side of the manifold from the cartridge. Like this ( looking down the bearing tube )

O bearing tube
!! magnet(s)
-- plinth

Note that my modified arm cable loom exits the arm wand in front of the bearing tube, it does not pass though the bearing tube.

Very entertaining Chris, much mirth.

"I took one of the small circle magnets from the ET2.5 setup over to my Dynavector tonearm. What followed kind of reminded me of one of those horror movies –you know the one where the guy wakes up and finds himself magnetized in a kitchen; pots and pans, knives start flying towards him getting stuck on him as he ducks.

ok - no pots and pans or knives here. But I did LOSE the magnet as it flew out of my hand. I had to search to find where it had lodged itself."

I initially used one fridge magnet then went to multiple fridge mags. Finally using Neodymium before abandoning the idea.
I tried first at the counterweight end then transferred to the wand end. There are differences. Now the reasons for that could be a whole new controversial discussion.

As per an earlier post, when I rebuilt the manifold I used 2 shims and one grub screw arranged at 120 degree increments each end of the manifold. This allowed for tightening by doing up the grub screws. Do this on a standard manifold at your own risk

You got me running to the arm to check these little screws. Still tight after 15 years, phew.

So now some may be asking why I haven't cleaned the sleeve in 15 years.
Well, we do have very clean air here in NZ.

With the air pump running I break the air line next to my pressure gauge and squirt in CRC CO contact cleaner. Then reconnect.
I have previously placed paper towels at each end of the manifold. Then move the spindle back and fwd.
The cleaner is forced thru the sleeve and its tiny orifices. Leaving them to be nice and clean

I do this approximately every 6 months with positive results.

Great thread and thank you to all that have contributed to this thread.
As a tangent tracking fan this ET thread is providing me with some very interesting viewpoint and insight on the working of this tonearm.

Richard - We are all big boys here and we all know this hobby has a lot of controversy as it is based on preferences. Please do share the differences you found.
