Model 89 coil rewind..did anyone save their notes?
#12

Quote:Why would I have to bake the coil?? 
If you don't, the oscillator my not work. Sometimes there is enough moisture in the coil form to keep the oscillator from working.

Bake the form first, rewind the coil then, spray a couple of coats of clear lacquer or enamel to seal the moisture out.
