sure would like to see how you did it and pic`s would be help full
I attached a picture of the finished element. Much trial and error would be needed to get the thickness right along with figuring out dampening it with rubber or something similar. The original element and dampening material were roached. Here's the procedure: The Rochelle salt powder is available on eBay. I paid $7.50 for 4oz. You mix the powder with hot water and strain the solution through a paper coffee filter. Let the solution sit in a shallow container and the crystals will grow. They are easily cut with a fine blade hobby saw and then can be sanded down to the correct size and shape. Like the two elements of a piezo wafer, you need two pieces of crystal that will vibrate against each other. The two elements are placed one atop the other and the two sets of contacts (one for the stylus holder and one for the wires to the amp) are each attached with one on top and one on bottom. This creates the piezo element or "bimorph". The contacts are held in place with foil tape.
