Eminent Technology ET-2 Tonearm Owners

Regarding the JIG ^^^^

I have installed the ET 2.0 and 2.5 on a dozen ? different tables of various design. During this time I have removed and re-installed the tonearm in whole or part maybe 70? times - mostly due to cart changes.
Audiophilia Nervosa phase.  An AudioGon search on "Goldilocks and the Three Turntables, represents a milestone in a way for myself, and reveals much, in regards to my personal adventure. 
  
Now regarding the JIG itself. 

IMO - the key to an easy and successful installation is "Flexibility" in the "Jig" and the "turntable design".

I can share thoughts on what I mean by flexibility if anyone would also like to share here. I am on the forum sporadically through the summer more so later in the fall . Hope everyone is enjoying their summer - or winter - 8^0 - down under.

Cheers

Hi,

I am wondering if any of you is having troubles with water condensations in the air bearing section?

I got ET2 that I refurbished (changed manifold sealing rings, removed and cleaned really well the manifold as well as aluminum tube that rides inside the manifold, etc...) but have a repeating problem with humidity condensation.
Was first using original aquarium AT pump at about 2psi and then upgraded to Medo AC0110 which delivers about 10-12psi trough my "buffering tank".
I run even double filters on input as well as water separating filter and then even added a silica air drying filter; still get condensation visible in clear tube where air gets into the tonearm as well as getting bubbles coming out between the manifold and the aluminum tube.
Result is that this compromises how the arm glides and makes the needle jump the grooves when playing.
By cleaning everything with alcohol I can get it to work well again, but it will just soon return with same problem.
I am using AT33ptg2 cartridge tracking at 2.1g, all mounted on SP10-mk2 turntable.
 If anyone experienced similar problems and found a solution please share your advice as I am sadly at the point of removing ET2 and replacing with conventional arm....

@sary,

Does the Medo pump you're using run constantly? If so, this may be your main issue.

No, I switch it on just when listening. 
The fact to consider is that there is pretty high humidity over here, but this happens always, even on "dry" days...

There is a challenge when one tries to run a full 360 degree air bearing in Mexico or the Amazon. Adding moisture to the air bearing will have the same effect, as adding water to the oil of a combustion engine.

This is not a good environment. The air pump system makes up IMO 50% (EFFORT not COST) in the set up of the solution.

This is not going to cut it unfortunately .You are trying to run a Porsche 911 at the track with snow tires.  

Recommend a pump system which eliminates the moisture at the pump, and a regulator / water separator near the air bearing, that allows you to see the PSI and moisture level near the air bearing.
How long is the air line - pump to air bearing ?  
Does the PSI get lower along the way. It is an indicator that water / moisture is getting in the line, if you are losing PSI.
