Eminent Technology ET-2 Tonearm Owners



Where are you? What mods have you done ?

I have been using these ET2's for over 9 years now.
I am still figuring them out and learning from them. They can be modified in so many ways. Bruce Thigpen laid down the GENIUS behind this tonearm over 20 years ago. Some of you have owned them for over 20 years !

Tell us your secrets.

New owners – what questions do you have ?

We may even be able to coax Bruce to post here. :^)

There are so many modifications that can be done.

Dressing of the wire with this arm is critical to get optimum sonics along with proper counterweight setup.

Let me start it off.

Please tell us what you have found to be the best wire for the ET-2 tonearm ? One that is pliable/doesn’t crink or curl. Whats the best way of dressing it so it doesn’t impact the arm. Through the spindle - Over the manifold - Below manifold ? What have you come up with ?

Hi Ketchup –
That phoenix wire looks interesting – is anyone using it ?

"the four individual wires are separated from each other where they are exposed in the loop. This arrangement had the least effect on tonearm movement."

You can see this in your system pic. So you tested it out both ways braided and separated ?

Is anyone else using the wires this way ?

LEVELING – heres how I do it. Can it be improved ?

Do not even attempt this if your platter/tonearm basic support are not already level. You guys with suspended tables – I feel for you. You are asking for trouble with this arm.

I don’t use the brass weights for leveling. It takes too long and you are also messing with the most fragile “I think” part of the arm. The Plank. (I Beam). I use Blue Tac and I add it to the top of the lead. If the VTF is 2.0 grams I make up a quick blob of the blue tac and add a touch more weight say 2.2 gms. Leave it next to the platform when not using it along with your level balances.

As the manual says you want the arm to free float.
Blue Tac in place. I position the arm above the lead in groove first and I start touching/tugging/poking the exposed wire with my finger. Lowering the cue lever a bit to see if I can induce movement. I try to see how much effort it takes to make the arm move. When u think ur good bring the arm to the end of the lp position. Repeat. This is where it gets frustrating because of counter forces. If your wires have “little” effect on the arm it should not move. In either position.

Now take the Blue Tac off – and try lowering the arm again at the start and end of the lp positions. Is it coming down straight ? If yes you should be good to go.
The wire effect is ALWAYS there you can’t eliminate it. What we are trying to do is reduce it. How detailed (anal) you are in doing this is the difference I feel between making this arm sound like nothing else out there or just a fabulous arm.

If your platter/arm setup is not level before you attempt the above you WILL pull out your hair doing this. Something could have gone out of level. Like the guys with the suspended tables. This is the main reason I feel most “previous” owners sold these arms. They are probably better off with pivot arms.

Can the above be tweaked better ? Is there a better technique for doing this ?

Recommendation – buy a test MM Cartridge whose tracking range is in the low say .3 – 1 gram range. Set this one up first. It will test your setup. I feel if you can make this one work well, your 2.0 – 2.5 gm MC will have no problem and will sound like it has never sounded before.


Cheers
Chris,

Funny, this morning I happened to see the post where I got the Phoenix Wire idea from. It came from Oilmanmojo here:

New Maplenoll Ariadne owner needing advice

He gives another source for wire- A-M Systems
Thx for the link Ketchup will read through - Olimanmojo, Rushton, Piedpiper, Frogman, a few others helped me to get my feet on the ground with my first ET2 years ago on a nice piano black VPI HW19 MkIV. I hope those guys see this and chime in here with their vast experience.

I still remember once I got it setup I could not figure out why it could not get through the last track. Turned out the original old pump was down 1/2 psi to about 3.0 psi. It was enough to affect it. The ET2 needs at least 3.5 psi if I recall to work properly. A Medo AC110 fixed the problem for $50 on ebay and helped raised the PSI to 7 or 8 psi.

Dover I am looking forward to your pics.

Cheers

Great tonearm. I have used one for many years and now sits on a VPI TNT6. High pressure manifold/Medo compressor (17psi), homemade surge tank, damping trough, and AudioNote silver wire in one continuous run from cartridge clips to preamp. I can't recommend this wire enough. In the years I have used this arm I have rewired it three times (Cardas, Discovery, AudioNote). The AN is by far m favorite with much more refined and transparent sound, although some might call it leaner than the Discovery or Cardas, but NOT harsh. My experience with the position of the counterweights is exactly the opposite of Slaw's. I have found that in my setup, further from the spindle is best. In fact, the best bass response and stability that I have achieved is with the weights about as far from the spindle as the cartridge is (in the opposite direction, of course). Coincidence? Tip: for best sound, do not over tighten the adjustment bolts!!!

More to come.
I have used an ET-2 since they first came out. It is now mounted on a TNT of early vintage (MK I, II??) which still has the spring suspension. I am about to convert it to the paddle ball suspension as soon as I can find some paddle balls and make up a few parts.

I recently plumbed it into my shop compressor so my tone arm is now driven by a 5hp compressor with a 50 gallon tank. I am running about 15psi but keep seeing 19psi as the sweet spot but I can't tell any difference. What is magical about 19psi?
