First attempt at rewinding an oscillator coil (Phil 38-12)
#5

You can try a hair dryer or freeze spray the see if you can get it to fail.If you think the coil is the problem. You probably don't with to rewind the primary but if you have a burning desire to do so you'll need a 1/2 wood dowel some small wire like 38-42Ga It takes about 120turns wound nice and flat/smooth. After you wind that use some duco cement to glue it in place. Secondary is wound over the primary same size wire about 40t cement too.

I'm sure the coil had failed because it was open. The wire I used to rewind is a close as possible to the original wire on the coil.
