Have you considered just getting a wall shelf? I don't think the marble and glass are a good idea and I would try it without them. I suspect that they are reflecting back the energy when you tap the table. You would be better off with a support that dissipates energy or a set up like Theo's. I have a similar Linn which I use occasionally but haven't noticed this when it is on my TNT stand or Star Sound rack. If there is a good Linn set up tech close I would have the suspension checked.
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.
