Rewinding tweeter voice coils must make brain surgery look easy.

It's not _that_ difficult if you have a binocular microscope, good
lighting and patience. The original wire has left grooves in the
varnish (as before). I supect that the original may have been done by
hand as there are slight traces of uneveness.

When I've looked at burnt out coils the former is usually distorted
due to the heat.

The former in this case is simply stiffened card and there's no burn marks
at all. So I think it must have had a relatively easy life. It was O/S
simply because the magnet had detached itself and ground the coil against
the pole piece breaking a lead wire. After reseating the magnet, the old
coil was a good fit in the gap.

Quite easy to rewind if I can get the correct wire. I've now weighed the
wire and it seems that my reading of the SWG by micrometer must have been
incorrect as the original weighs 0.196gms, whereas a similar length of what
I thought was the right gauge weighs 0.303gms! :-(
