F 1540 valve car radio
#1

Hi there, I am working on a Philco F1540 car radio.I discovered that the oscillator was not working well .I removed the oscillator  coil and found that the coils more or  less disintegrated when I pointed the heat gun at them. I was able to salvage some of the coils and discovered that the outside coil,wound in a cotton covered wire seemed to have 20 turns.But the inside coil (wound in enameled wire ) broke in several places.I have rewound both coils estimating the number of turns  but the tuning is off. Does anyone know how many turns there should be in each coil?Cheers, David
