Hi all
I have to repair a Supex AL-2 tonearm lift and after some googling I believe I should start by filling the piston area with silicon fluid... My question is: What viscosity should I look for ? 1000 ? 50000?
PS: I am not sure but I believe this lifter is also used in the Fidelity Research FR-66S tonearm.
Hope someone has had experiences with these lifters....

I saw here Silicone Damping Fluid For Tonearm Cueing Mechanisms, Damping Troughs and Monopivots that one should use 300.000 centipoise fluid for tonearm lifter.... somehow it seems quite distant from 10.000
Sorry to be reviving a very old thread.
Just got a beautiful old, Suprex AL-2. The mechanism works smoothly up and down. But it does not stay in the up position. When you release the lever, the lever and piston slowly return to the bottom.
Would appreciate thoughts on repair. Thanks.
