Did you bake the coil prior to rewinding?
Moisture absorption is a serious problem with 19 and 89 oscillator coils. Sometimes, even baking does not help.
When I bake a coil, I literally put it in the oven (or electric toaster oven), standing upright on its steel terminals with aluminum foil underneath to allow a disposable surface for the wax to melt onto, for 30 minutes at 200 degrees Fahrenheit. This does not harm the coil form. Don't cook it at higher temperatures as that can ruin the form.
