Ok, it took me longer than I thought (fucking servicing an EMT is a nightmare for me),
but I've finally put the TT on the rack:
It's all still a bit provisorical as the inner cage is not fnished yet (the suspension is missing), but I could test the
pneumatic table. It works! I can jump on the floor, kick the rack, hit it, etc, no audible feedback.
Good. Those tons of steel and sand do seem to work, at lest in the no-acoutic-field condition.
The spectrum analyzer sees an increase in the few Hz-100Hz region during a heavy footfall, but it's inaudible.
Soundwise I was not expecting anything but as a little present
I got a quieter background, the sounds seems "cleaner" (paradoxically at MF/HF), better articulated.
I've also changed the plinth from plywood to slate (the one in the picture).
The change is subtle (I'm also too tired to make a decent comaprison),
but the plywood seems more "wooly", slate more "sparkling" although I think
it transfers a bit more rumble. Not to say I prefer rumble, but the sparkling nature of the slate
appeals to me so far.
Next: finishing the insert (I mount a pneumatic suspsension under it too)
and checking cones vs large feet on my floor. I also have the ball bearings already
machined but so far little motivation to try them.
Cheers,
