Weird damping mechanism- ever seen this?

Posted by mr.bear (A) on July 11, 2017 at 21:54:59

Anybody ever seen a damping mechanism like this- no piston! The damping on my sweet Sony PS-X50 is gone and I aim to get it back.

The cueing lever is on the front of the table; it moves the cam that actuates the cueing lift-rod. The damping fluid is between the faying surfaces of a bearing that supports the rotating "lifter cam assembly." There is a normal-appearing cylinder holding the cueing rod but it's a fake! - not a piston, just a guide for the rod.

I almost removed the tonearm to gain access to the "fake" damping cylinder cast into the base, a mess considering the automatic stuff, before I saw the sketch. I can take off the e-clip, open the bearing a bit, and add oil with a needle injector, without removing the arm!

Any suggestion as to what kind of damping oil to use? I'll contact the nice folks at Turntable Basics and ask them also. Thanks.

Some pics are the wrong data format.. You may have that turned off, or - 3+4=5 11:27:25 07/12/17 (1)
