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 ?

Richard its never the best way to just cut and past portions of emails and other info into a thread. Whats missing is the rest of the email, and the valuable info obtained from verbal conversations.

Summary:
Pump/Surge tank ---- long tubing (if you don't have the room coil it up) ----- ET2
PSI Gauge/filter within 5 feet of the tonearm.
The PSI coming out of the air pump should be ideally targeted to match the PSI the manifold has been designed for. For those buying a used ET 2.0 (.5) its important to determine this. We have discussed the technique here. Before this technique is performed the manifold needs to be restored.

Definition of a manifold.

"A pipe or chamber branching into several openings"

Two Et2 Manifolds

The owner has provided permission for me to post these pics. Thank u !

The one on the left dirty from years of use without a filter/trap. The one on the right has been cleaned. What can't be seen in the pic is what the insides looked like before and after. Its the same manifold.
Cleaning procedures well documented in the manual.

If your planning on upgrading your pump make sure your manifold has been restored first.

The threaded portion of the manifold is designed to allow air to spiral around the outside of the set screws and maintain the precise length and size of air passage required for an efficient air bearing. Page 42


Next in Line.
The Air Bearing Spindle psi requirements are less than the manifold as only a portion of this air is required for it to float properly. Approximately 50%. That means on a base ET2 only 1.5 psi ! - if your manifold is restored and functional.

The "old" air escapes as per Bruce' design out the sides of the manifold.

Richardkrebs - you must have time on your hands...

I fail to see the relevance of your comment. If you're really that interested the previous post took 40 mins - which is about how long it normally takes to down my mug of coffee with one re-heat. The intent (agenda) of all this includes awareness, interactive sharing, knowledge, learning, and "mostly" fun. I am having a blast. how bout u ? A fun start to my day now that I am not living with the bears.

Now where were we ? Something about the similarities of the ET2 VTA and a brothel ?
Chris.
Sometimes these posts can be unintentionally blunt.
re the time thing. I meant that you always seem to be prepared to spend your time researching and sharing your extensive knowledge on the ET arms. I personally have learnt much from your input, which is most appreciated.

I look forward to the brothel post!

cheers
I haven't felt this much pressure for a post since I stopped reporting to a boss (wife not included)
you guys prove once again that sex sells well even if in theory only. Now to come up with something that is pertinent, force us to look at ourselves, chuckle a bit, maybe destroy another audiophile inspired myth along the way ......and do it in a way that doesn't give cause for audiogon gods to delete it. Is such a post possible ?
project time management reporting

the previous post took another 40 mins.

First 20 mins to think it up, type it, push submit (all while being distracted by a puppy that seems to want to chew my leg leg off if he doesn't get 100 % attention)

another 20 mins for the system to return a successful post message. maybe some system maintenance ? maybe a little bit of audiophile exaggeration.
