Eminent Technology ET-2 Tonearm Owners

This is in my system with two twisted naked 0.1 mm silver wires, two L/R independent caple looms in a ca. 10cm diameter, very low torque on the arm apparently.

You have spoken repeatedly about your wire setup but have never been generous enough to share pictures of it to those in this forum. It is a new year and pictures are worth a thousand words. I ask you to share again. if you would like send me the pic and I will post for you.

From my experience the best wiring setup is to have the wiring come off the armtube down into a happy face loop. I discovered this during my armpod experiments. The wires, going down into a happy face loop after the armtube have the least effect on the movement of the air bearing spindle. Remember the ET2 is a free bird, unlike say the Kuzma Airline for example; does not need the wiring and airline for damping. Different design. Those that have wiring arranged in a Kuzma Airline type setup, on their ET2, are asking for trouble. Your wiring is controlling the spindle and will make you think maybe things are not level with its pushes and pulls. My Verdier uses a tall Solid Aluminum pillar for an armboard, that is bolted to the plinth, so the wires come down naturally. The ET2 really does like to be placed on a pedestal. I show pictures of this wiring set up on my virtual page.

I am reposting a thread archive shot of Frogman’s wiring set up for everyone benefit here also. Frogman, I hope you do not mind ? 8^0

Frogmans wiring

For anyone using a plinth that was fairly flat with the armboard (like here with FM’s TNT), this is IMO, a great arrangement and the way I would do it also, if I had a flat plinth. Notice the happy face loop coming off the end of the armtube.

Hi Chris,

I guess I’m missing something regarding the post I made above. and then your response...

How can the VTF not be changed when one changes VTA by using the arc block design of the ET? This will either move the overhang out or in depending upon the necessary adjustment....right?..therefore altering S2P distance and VTF.

From my memory, this fact is not stated in the manual

...going only by memory???

Early on in this thread I addressed this issue this way... when I set up the arm, I used my most played record weight/height/thickness as my reference and used this to set up the arc block in (it’s center) regarding the latter record height preference. I referred to this as the "neutral zone".

Any deviation from this "zone" is a result of a VTA adjustment on the ET’s arc block that alters in some way the SRA, the S2P, the VTF. None of this is mentioned in the manual.

So... as all of this relates to why I posted above to another member...

He had so many system changes in play, and seemingly a lot of basic arm set-up issues, yet seemingly wanted a direct response to one/two issues..... Impossible!

Regarding your VTA question - I find it rather odd from a previous owner/user of this tonearm ...how many years ? ... to be asking this question. This ET2 patented VTA feature is in fact what distinguishes it from all other tonearms including other air bearings. Bruce understood that records come with varied included cut angles, so he designed a tonearm to easily deal with them. 

Now the smart designer in whatever field, would never discuss secrets about how a patented design works .......in an Owners manual.
  
To use this VTA feature properly, and to see how it executes, is to understand it. Period. And we have discussed it in this thread previously.  
  
Your question therefore indicates to me that either your setup was off, you just never understood it, or maybe a combination.

As some of the ET2 owners here are Johnathan Carr fans I will let him re-affirm things.

This is for SLAW and it is also for PEGASUS

However, as I recently wrote in Stereophile, the construction of every tonearm that I am aware of (with the sole exception of the Eminent Technology linear trackers) guarantees that altering SRA will simultaneously cause the effective length to change, along with the tracking force.

To make sure that any SRA-induced audible changes are truly attributable to SRA rather than sundry alignment shifts that came along for the ride, you must recheck the overhang and tracking force and "put them back" to what they were prior to the VTA change.

At the end of the day, you may ponder about the real value of "VTA on-the-fly" mechanisms (grin).

Hi Chris,

I’m still an owner. Plan to use it again at some point. If this negates me asking questions, well....that’s for you to decide.

You keep referring to the owner’s manual in almost every case except for mine? "Now a smart designer in whatever field, would never discuss how a patented design works.....in an owner’s manual".

#1 Why not?
#2 A patent is public knowledge for those who ask.
#3 Am I still missing something?

The arc block. Emphisis on (arc). Am I still missing something? When adjusted..moves the overhang slightly backwards or forwards. Doesn’t it?

The quote from Steven Carr seems to me at once confirm my post.
