Hi all. I got a telefunken dynamic mic on ebay the other day and guess what. it was dead.

I managed to get the capsule apart. nice of telefunken to use some kind of waxy substance to glue this together. Anyone know what that might be? Beeswax?

and I managed to get the voice coil diaphragm off and in relatively good
condition.

as you can see, the wires that go from the coil out to the edges of the diaphragm are totally gone... they were there, like a black wisp of cobweb, until I sneezed and they dissapeared.
I have to replace the wire to each side of the round copper voice coil...
Any tips on what to use?
I'm thinking some enamalled magnet wire-it's the smallest gauge wire I have- and conductive epoxy?
whats the best way to get the enamal off of the end of magnet wire?
Anyone have a better idea?

Thanks
Kelly
 
just thought I'd place this info up for grabs.
tried conductive epoxy and the magnet wire.
didn't work the first couple of times through, but with a little practice I finally got conductivity all the way through the coil, as I'm pretty sure that's what I was after.
never worked though. threw the capsule at a wall, it didn't work after that either. looks like a wm-61 might find it's way into that mic housing at some point.

toasted, but the conductive epoxy did work at gettink wires reconnected to the diaphragm. next time.
