The Advent Loudspeaker - disassembling the fried egg tweeter

[kwingylee]

Has anyone tried to disassemble a fried egg tweeter and successfully replace the damage voice coil with one from a donor?

Go buy another one on eBay.

Have you taken it apart to see what the actual issue is? Broken tinsel wire, burned voice coil, etc?

Yes I did, broken wire. I cannot figure out how to remove the diaphragm without destroying it.

I’ve repaired Wharfedale Mylar domes by peeling off the dome and then unwrapping the tinsel wire off the VC until I had enough to reterminate it.
I could see the dome on the fried egg tweets being a little more fragile and harder to get off in one piece.

I have a fried egg that works but has low output. Maybe I’ll try peeling the dome off to see how it goes. I might have another one that’s good. I’ll have to look in my stash.

The cones/diaphragms of the fried egg tweeters are fairly brittle. I have one from my very early pair of OLAs (it has no metal grill attached) that has a lead broken right where the lead enters the cone and I have been putting off repairing it because I know it won't be easy.
