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....
