LP12 suspension susceptible to acoustic feedback

My turntable setup: LP12 (early 80s model, unmodified except for Nirvana springs), Syrinx PU2G, Shure M95-HE.

When I place the arm/cartridge on a (stationary) LP, the entire arm board and arm rest resonates to light finger taps, and the sound emerges as rather loud thuds through the speakers, at normal listening levels.

When the arm/cartridge is lifted off the LP, the feedback is minimised.

My LP12 rests on three light wooden blocks (the sort kids play with), a marble slab, a wooden slab and four sheets of thick plate glass, in that order.

I'm thinking of getting an IKEA Lack table for the LP12.

Any solutions to eliminate, or minimise the feedback?

Thanks.

Thanks Theo and Stanwal. I have not considered wall mounting.

By the way, I forgot to mention that the floor of my apartment is solid concrete and tile, so I have no issue with footfalls, unless there's an elephant in the room :)

If there is too much mass underneath (and I suspect Theo and Stanwal are right about this) the lightweight IKEA Lack table may be the answer.

Thanks.
