I can get 0.6, 0.8, 1.0, 1.2, 1.6, 2.0 mm thicknesses. 0.6 & 2.0 cost extra. It's unfortunate that 0.5 is not available, but I hope that the 0.6 will still prove acceptable
I thought that for the stator the stiffest one at no extra cost was the one to go for, but 0.8 is the same price. Do you think there is an advantage to the thinner one? In sound quality?
I have kept the capacitance as low as I could conveniently, I can maybe improve it slightly.
The prices are...
