Thread-topic: Emergency Secondary repair, also archives down???
When I fixed mine, I removed the offending turns + 1 or 2 on each side, did some light sanding to remove any burned PVC/Poly.
I sanded about 1.5"-2" of wire on each side,overlapped in the new wire and soldered.
I then space wound 2 or 3 turns in the void, As its hard to solder right next to another wire without burning the enamel of that wire too while its up against the pvc etc.
Put on 10 coats of spar varnish.
It was pretty hard and the result looked like crap. But it worked...
I ended up making a new seondary anyway and trashed that one.

Hey all.
So I finally burnt up my first secondary coil, (hopefully my last
also) and I was going to show it off on Saturday (not a paid gig, but still
I'd rather not disappoint). I was going to look up the accepted procedure
on repairing them in the archives like a good boy, but they didn't work on
my machine, I got a 404 error... Well the error occurred when I tried to
"search the site including archives". Anyway, is there any last second
pointers for the uninitiated? The coil is a 4*18 wound with 28 AWG, is
there any chance of saving her? The turn got hot and smoked a bit, before
glowing red, it is pretty bad, but the damage seems confined to about 3
turns or so, about 2/3rds up the side, it suffered a fall at some point and
despite re-coating it with polyurethane, well you know the story.
Scott Bogard.
