An Idea for the old school when you can't find an EMT 140

Steel plate suspended in frame, Amp driving transducer at one end of plate, Barcus Berry pickup on other end of plate.
I might make one over summer.
Any constructive input welcome

There's also the Vidsonix Ghost driver for around $20 which has a flat face with holes for attaching it to the plate. http://www.vidsonix.com/vidsonixnew/info_vxgh72.htm
I used one of these on the plate I built...using a large old bbq lid as the plate :) haha, Worked really well.
The sound exciters would have been my next choice. They look funky.

Your post Alastair has had me researching home made plate reverbs for the last few days and I would also like to build one for our studio so If you would like a partner this summer I would like to make one with you.

What I have read sofar (thanks too Ian for the PDF) is that Steel is preferred over Aluminum, being able to tension the sheet is important for tuning and having a dampener helps to control the reverb time.
According to one source EMT used a 1-meter by 2-meter cold-rolled steel plate approximately 1/64-inch thick. http://www.prosoundweb.com/article/prin ... ate_reverb
The same source suggests testing the sheet with a key to assess its tone when selecting it, which makes sense to me. Here is their shopping list-

Plate Reverb Required Parts
1 x Steel Sheet (your choice)
Approx 30 feet x Tubular Steel or Angle Iron (for frame)
10 x Threaded Rubber Coated Mounting Hooks
10 x Nuts (to fit Hooks)
10 x Rubber Washers
10 x Fender Washers
1 x Driver (your choice)
1 or 2 x Pickup Transducers
1 or 2 x Preamps, DI boxes, Transformers for Pickups (if needed)

Optional Parts
1 x Case (your choice of style and material)
1 x Damping Mechanism with Absorptive Material (your choice)
Suspension Method (to isolate plate and frame from case)

Just thinking out loud... what about an old unused trampoline frame with the legs cut off for the frame??? :)
