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 ?

I don't have a damping trough on any of my arms. Rugy, what upgrades are you getting and are you talking about a group purchase the troughs? If so, I am in.
I dont think the seller knew much and may have been selling for someone else. No indication he know that the two arms were even different from each other.

but, I will try your plastic piece idea.
does anyone know if there is a downloadable mounting template for the ET@. I have two of them, an I want to mount it on my custom Lenco, but I'd prefer not to start dirlling unless I know for sure what I am doing. I have dowloaded the manual, but it really doesnt give enough accurate info on mounting, mostly because you can buy a metal template.
anyone have any info?
Is there a way to tell if I have a high pressure manifold on my ET2? Some sort of marking on the manifold, or a different size? I have a couple of different pumps, but dont want to put on a higher pressure if its going to damage something
Yeah, I picked it up. Didn't realize the carbon arm, but I really wanted the jig. This is my third.
yeah, saw the ad. My system has enough going on without adding a step down transformer.
Yeah, I have 3. Or will have when it gets here, one for the lenco ptp, sp10 and then maybe the empire 208.

Cool air supply though.
It looks like the arm is the magnesium version. Isnt that what came with the 2.5? Is there any other way to tell?
Yeah, its the step that suggests to me its a magnesium arm, but it should arrive today, so I will check. That being said, is there any other difference between a 2 and a 2.5 than the spindle or manifold size?
I think I've got the 2.0 with the magnesium arm. All my spindles are the same size
Yeah, I am now looking into creating an air supply system to run all 3 off a single supply. I intend to include separate filters for each arm and central water collection off the surge tank. I have a medical grade air pump, but I could just use my Wisas, either alone or parallel into the surge tank. I need to get a better guage and regulator to try playing with different air pressures. right now I only have one running, on the PTP Lenco L75 along with a Helius Aurora 10". I need to go back through this thread one evening to remind myself of the various tweaks others have found helpful.
Do you think there is a markup for medical equipment?

I just purchased the same pump on ebay for less than $50. good thing Bruce didnt see this.
Oh, lord, got two more et2s. Maybe one will be a 2.5 with the high pressure manifold. 3 more arm wands too, one definitely magnesium. Up to 5 now, so 2 go on the SP10mk2 and two on the Lenco PTP. Have to think about No.5. Maybe on the Empire 208.
Ct,
Well, first of all, I like both the design and execution. I had two, but never really set one up well, and sold one to a gent in Australia along with a few cartridges. He wanted an arm for his sp10, so I tried my et2 on one of mine to see if it would fit. Around the same time I acquired a surge tank and very quiet Wisa pump. Anyway, I set one arm up on my sp10-2 and the other on my lenco L75 PTP and took my time setting them up, and you know, I was really impressed. Then I wanted to get an oem template and mag arm, which came attached to another arm. This last pair came on a whim offer which was accepted.

I have a thing for out of the box thinking, interesting design and small manufacturer craftsmanship. The et2 fits in with my audio mods, Helius, sme, alpha son arms..

So to answer you question, I don't know.
Well, the package arrived today, very well packed. Two Magnesium wands, one aluminum, two full et2 tonearms without arm wands but with damping troughs installed. One extra base, one extra arm lift rod.

One of the arms has a 19mm tube, the other 16mm, so am I to assume that the bigger one is a et2.5, or has a high pressure manifold? Have I finally got one after 6 purchases? (i had sold one earlier this year)the fatter one looks a little newer too, less wear on the writing, but both look in very good shape.

Big honkin air chamber. 6" pvc about 2.5' long. Big pressure guage to on the air chamber, and a bunch of little parts like vtf weights and arms. I'll get them up and running, and see which I will keep, and on what.
I have some extra I beams,but not leaf springs. What is the advantage of multiple leaf springs or am I now entering another world of obsessive complusive behaviour.

Yeah, the tank is much bigger than my previous 4" round, 18" long chamber. What PSI does the et2.5 run at?
