Hello jay:

Yes, I had an older model on the Pristine 2. I think I purchased them back in the mid 1990s.

Since then, diaphragm change, copper diffusion ring, power supply, back plate upgrades, new Reg. bias supplies and a special order design modified 560 base focused panels fitted to the pristine 2 metal frame. Roger says there is nothing more I can do with these backplates.
