For kickers...

Imagine that table setup in your room and the orientation of the ET tonearm. This is very important. What kind of track will that tiniest of signals run on ? Will it be a long course or a short one. We calculate the length.

Measure the length from the headshell running along the armwand straight across and into your phono stage inputs. We add some length for a happy face loop. Then we get Gene (or somebody like) to build you some straight shot wiring.

*****************************
Wiring Effect on Mechanics 
Unlike for example the Kuzma Airline, the ET tonearm does not need the wiring as a cradle. But its very smooth bearing, can make the wiring a problem for the ET 2, if not orientated properly. 
 
For this reason, the single shot wiring gets added last, after you confirm the tonearm works well mechanically. By adding in the wire after, you can verify setup, and you can confirm how much effect the wiring has on movement.

Just some Out of the Box Setup advice.

oh and you call Bruce and get him to send you two long I Beams setup with single and double leaf springs.

Then the fun can start.  

Well I guess the seller got all huffy at my offer ( which was not that low imho).
He responded with the fact that he had already reduced from 2k to 1799 and was not open to any further reductions.
When I then pointed out that he still had his listing stating or best offer, he then blocked me from making any future offers or dealings with him.

TBH with that type of attitude I think I got away with a potential headache if lets say had been damaged in transit etc.
Sorry Chris but looks like I am still on the outside looking in!

In the process of setting up a LP12 for a ET2.5 tonearm. Is the aluminum mounting base a noticeable improvement?

Hi ncampbell

Have you decided on the spot to put the ET mounting hole ?

We discussed the Linn LP12 here last year. I did a quick search of emails and found the email trail with Bruce which I attach below for you.
Hopefully the information helps you.

I remember the consensus at the time was that the ET tonearm mount hole should be positioned very close to where the pivot hole is.
So the ET 2.5 is mounted at an angle. The reasons due to the suspension designed for a back mount. This is referenced below.

One way of attaching the ET 2 mount is to get a long enough Stainless bolt and nut with a large - small holed flat washer (Fender Washer) that itself is larger than your mounting hole.
The washer will hold the bolt/nut tight and you can mount the ET base to it.

re: aluminum mount.
It has more heft, you can feel the difference in your hand when holding it.
So as you are already dealing with a tricky suspension - I would forego it for now and go with the original carbon fiber.
And then add the aluminum later if you like. JMO.
I can tell you that the solid aluminum joint (gooseneck) for me changed resonances enough that the MM cart I was using became un- listenable
with my 2.5 and Mag armwand. My turntable supports the aluminum mount with no issues.

This is probably the best strategy, the Linn, which is an
excellent turntable, is designed similar to the original AR turntables 3
point spring suspension with a low natural frequency. The drawback is
that the repositioning of 20 grams or so as a straight line arm
traverses the record may deflect the suspension, I have not measured a
Linn to know if this is the case.

On a three point suspension like the Oracle, the ratio of masses
was such that this was not a problem

Bruce,

"designed for a lighter load centered on the back side of the

From what you are saying, the ET2, if this person really wanted to do
this set up, should then mount it at an angle on the plinth at say 1pm, as close to
where the pivot arm is mounted ?

This has been done a few times, you need to be very good with
turntable set up, and it’s not ideal.

The Linn suspension is designed for a lighter load centered on the
back side of the turntable where a conventional tonearm mounts. It has
been done but the potential user should be very good with tonearm setup
and adjustment to complete the installation.

Someone is asking if he can mount an ET2 on a Linn LP12 turntable.
I think the suspension is not appropriate based on this video. I have
never owned one.
Do you have customers using LP12 turntables ? Thx. Chris

Thanks for the great pointers. I am going to start by mounting the tonearm using the current pivot hole with the fender washer suggestion. At that point I will measure suspension deflection to see if it is factor and if so try some different tonearm angles to see if the deflection can be minimized.
