I take it this mod requires resetting of suspension on TT's with floating sub chassis/armboard assemblies.

Correct - see my post #6

Oh I do love this site

Just tried this little trick on my 750db and it has made a notable difference.

Thanks Nick - it's quite good for something that can be tried for nothing!

A couple of points - this tweak works with the Jelco SA-750 series because the top part of the arm is one-sided and it's therefore free to resonate and a bit of mass controls that resonance very nicely The FR64S is one-sided too, so the same trick works. An arm like yours has a solid and symmetrical cap that will clearly not resonate much, if at all, so I would not expect you to hear any benefit, particularly with a record stabiliser weight that is way too heavy to be sitting on your arm's horizontal bearings. With the Jelco SA-750 there is no additional load on the bearings, so no risk.

yes, it was meant tongue in cheek
