I did part of the old Chadwick mod on this tuntable by getting rid of
masonite bottom board and putting leveling points at the bottom. This
made a wonderful improvement in sound from the way it was. The only
problem is : on my soft wood floors, it is very ease to jar the stylus.
Specifically, is there an adjustment that I can make to soften the
suspension so that it would be more like the original AR turntable
whose suspension it was based on? (thus making it more imune from
external vibrations). Suggestions/instructions for softening
platter/arm suspension appreciated...Dave

Place the TT on a large sturdy shelf securely attached to the wall.

I would like to second Norman's solution. I did exactly as he described with
my TD-165 and it worked like a charm! (This was about 20 years ago)

Softening the plinth/arm mount is not a good idea, but removing the
coupling you have via the spikes is. You could try some very soft, say
Navcom, Sorbothane feet. The best solution is to leave the spikes and
then rest the table on a custom made "sandbox" with a thick board
resting beneath the table and on the sand as it's base. This will
dissipate any external energy before it reaches the table. It works
similarly to the removal of the masonite bottom as it does not allow
resonances to build, yet it removes the coupling with the floor while
maintaining rigidity in the deck itself.
