38-12 Oscillator Replacement
#20

Unless someone has used the same "universal" oscillator coil installed in the same receiver and had satisfactory results, IMHO this coil is not working here...

You have provided one picture of the oscillator coil in question, apparently it "looks" very good... If a couple more images could be posted to this thread, I would be encouraged to look through the used coil box I have to see if I can find an identical coil... The images may also help someone else look in their storage too. Radio part "junque" boxes rarely label parts as to their source so it is a visual comparison...

Again, if the coil form and the windings are intact, meaning no attempt to unwind, thus loosing the turns count the old coil could be re-wound...
