rumble issues - see old thread update

Hi Doug,

Thanks for the clarification on your Sorbothene implemenation, as well as the validation that locating it closer to the source component is a non-starter.

Cheers,

What I find bothersome about the MinusK, and I fully admit I have no experience with it, are the reports of these going into oscillation by something like a cd drawer opening and closing. It seems that they do dampen out and work, but I can't imagine my gear on top of something that moves when queuing a record. I suppose I'd have to see it, but it doesn't sound comforting. :-)

Finally resolve what was wrong

the feather test - moving a feather lightly against the cartridge parallel to the record should move  the headshell

If not the tonearm bearing isn't moving properly


The tonearm bearing wasn't moving suficiently so the cantilever was moving up and down causing all the pumping

had the bearing fixed
