Default Re-Plinth DP-1100 Turntable.

I have a DP-1100 turntable, that is reasonably nice. The one big drawback is that the plinth is resonant - thin, cheap wood.

On a whim, I did some trolling around on Ebay and found some sources for bamboo butcher blocks. There are some large enough that they look suitable for a TT plinth. Bonded bamboo might also be reasonably non-resonant - its certainly heavy enough to do the job. The butcher block are also pretty good-looking. Has any one tried something similar? Another possibility might be cloth-laminated phenolic resin, though that stuff gets fearfully expensive in the size needed for a plinth.

I'd give it a try. Bamboo ply certainly works well for speaker enclosures, but it's expensive. Pretty sure I've seen the Bamboo butcher block material used for plinths, just don't ask where.

Hi,

I'd suggest hi quality marine ply, say 1/2" laminated to 1.5"/2".

That means you can simplify the cutouts to simply holes in
each layer and end up with a simply built complex structure.

rgds, sreten.

Depending on the details of the DP-1100 I'd want to couple
the two together for large flat underneath areas, YMMV.
You might also think about upgrading the arm.

Don't know if your platter is like my JVC QL-10 (in storage) but you might dampen and rebalance the platter along with the new plinth.
Most of these Asian DD,s focused on the motor back then and basically forgot about dead platters
I,ll bet you hear more differences there than the plinth, but certainly both would help.

Regard
David

I was looking in particular at a 18" X 24" X 2.5" butcher block made of laminated bamboo listed on Ebay. It's surprisingly cheap for what it is (the shipping is almost as much as the item costs, as it weighs >20 lbs).

Dunno if that's the case, but if you load up Google with "Kitchen Basics Bamboo Block" you get all sorts of blocks made of all sorts of woods, any one of which would probably make an awesome plinth with about 50% of the work done for you.
