I have had these for about 10 years, bought second hand. At that time, they needed a complete rebuild of the wires glued to the Mylar diaphragm.

Amazingly, the company still supplies kits to repair a product produced in 1988! At the time, I replaced the wiring on both panels, and they have worked brilliantly untill last night. Alas, the right tweeter (very fine enameled aluminum wire) has failed. I will have to open up the speaker strip the old wire and re adhere a new run.

I will share some pictures of the construction and process... but it will have to wait a couple of weeks until after the holidays.

Cheers

Ed
