This thread is of great interest to me as I am planning on building a 34" turntable stand in the very near future. Wood to be used is solid purpleheart for the structure & shelves with solid maple drawer face and ebony inlay, no mdf for the shelf core. Don't know if this is the way to go or not as mdf may have better suited properties for control of resonances (higher density).
Problem is I want to include a drawer to store the miscellaneous tools, cartridges etc. to reduce clutter. I really haven't seen a rack with drawers and am concerned about resonance vibrations. Design is similar to the zoethecus supplied by cfb but with a drawer under the top. shelf. Any input from anyone on this would be most welcome.
