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 ?

Slaw -
With regard to the aluminium plate/acrylic. I would not run the plate, it's added resonance. I have moved away from metal spikes, and if I use them I radius the tip so it is not a sharp point. I say radius, as in rounded, NOT flat. The idea is a small radius tip sitting in a larger radius hole as per most unipivot bearings. My suggestion would be to radius the tip of the grubs screws and then you should be able to couple directly to the acrylic without damaging the surface. In an ideal world the acrylic would have a dimple in it for the radius tip to sit in.
Slaw, working with AN wire is a delicate process, but with patience and care you can do it. Nandric's suggestion of anchoring the clips (one at a time; of course) on an old cartridge is a good one; you don't want solder "creeping" into the clip's sleeve. This can happen even if you hold or secure the clip vertically. A toothpick stuck in a large ball of modeling clay (or similar) also works well. The advantage here is being able to adjust the angle of the tooth pick/clip easily; horizontal is best.

-With the clip secured to the toothpick or cartridge, tin the clip's tab over it's entire length. Don't use too much solder; you don't need much.

-Now comes the hardest part; tinning the wire itself. After a lot of trial and error, I have found that the best technique is to melt a bead of solder unto the the iron's tip and with your other hand run the end of the wire through the bead of melted solder until you can see that the wire is coated with solder. Don't hold the wire in the solder bead too long or the wire itself will melt. Run it through slowly; it may take three or four times. Once the wife's insulation has melted the wire will be coated with solder; not before. If you try touching the wire with the tip of the iron you will probably melt the wire.

-Now, solder the tinned end unto the prepared clip's tab. I like to make sure that a little bit of solder (remember, don't use too much) runs unto the wire beyond the tinned section. This will provide some strain relief, as the insulated portion will be less susceptible to fracturing.

-Slip the heat shrink tubing over the wire unto the clip, making sure that it slips on past the tab and unto at least part of the sleeve for additional integrity and strain relief. Don't try to slip it on over the clip first.

-Unless the heat shrink tube fits very loosely (unlikely) I prefer to not heat-shrink it. This makes repairs much easier, by allowing you to carefully slip it off of the clip and reusing it.

Good luck, and let us know how you like the AN wire; it transformed the sound of my analog setup.
****Once the wife's insulation has melted...."****

Cracked myself up. Once my wife's insulation has melted, my iron.... Well, I better stop there :-)
****Once the wife's insulation has melted...."****
Frogman for me this wording conjures up a very vivid and clear image.

Its at this point “once the wife’s insulation has melted” that she comes downstairs, knocks on the door and tells me in a stern voice to add more insulation to the ceiling and walls of my room. :^(

My apologies for my feeble attempt at Balkan humour - I have probably left myself open to ridicule now by the humour master himself.
All of the tips are greatly appreciated. Tinning both the wire and clips sounds logical. I've finally decided on armborad materials and will probably start that project first because of the familiar sound of my system at this point.

Frogman: In dressing the AN wire, did you twist the 4 wires together at any point for possible noise rejection?
