Any suggestions for "foot fall" problems?

[PHC1]

Also watch the weight distribution of the balls. Place an extra amount towards the center of weight. In my case, I started out like this and had to eliminate one on the right. So I had two left side, one centered and one more centered on the right.

Thanks Serge ! I Will try both reducing the balls number and their situation.
You see : you can be a great experiencing guy !
You should let David experience the Men 220 by himself !

Why?? I never met a wall I couldn't patch -- unless your wall is mirrored, gold-leafed, paneled in book-matched walnut, etc.

This house has 3"X12" floor joists, and is extremely well built (1930) but there must be just enough movement in the fir flooring...

Actually, 1930's wood framing allowed much more bounce than today's structural standards permit. Longer spans were allowed (for a given joist depth) with more space allowed between joists. It would be best however, if you placed your rack against one of the long walls, where (typically anyway) all the joist ends attach. The joists usually parallel the short wall (to span the shorter distance), so the first one is out from the short wall 16-18 inches, and another 32-36 inches away; and they both deflect quite a lot, especially at mid-span (in front of the center of the short wall.) By comparison, there's very little deflection of the joist (ends) anywhere along the long wall.

Early wood framed floors are very bouncy. They were allowed to deflect quite a bit -- up to 1/360 of their span (any more would crack the plaster ceiling below ;--) Long wall is your best bet. Or an unsuspended TT.

Pillows, and balls, and cones, and Stillpoints, and Roller-Blocks, and Sorbothane, are all variously good at draining/damping vibes coming FROM the TT, but not incoming

Hey Guys,

Thanks for all of the tips. I had a great conversation about TT's with Jeff from AV Solutions tonight.

As many before have said, Jeff really know his stuff. AN encyclopedia of TT knowledge, and great guy to talk to.

Not only that, he fixed my "foot fall" problem.

He suggested putting a "wedge" between the stand and the wall behind it. I made some wedges, snugged them up.

Viola ... no more "bouncing tonearms..."

Thank you Jeff!!!

Jeff at A/V Solutions is a first class guy for sure!

I was at first impressed with a Ginko Cloud 11 platform until months later I was playing around and when I thumped on the TT base, it was amplified thru the speakers. Vinh sent me a couple more balls (in addition to the 6) and regardless of 4, 5, 6, 7, 8 balls; it continued. I ended up removing it -- and no more thud sounds when I tapped on the TT.

Maybe the Ginko platforms don't perform as well with heavy tables (close to 60 pounds).
