Hello,

I recently bought this model, and during usual cleaning it turned out, that somebody was probably trying to re-tune UKW to 65-73MHz. The result is visible in the attachement. Of course, I want to restore it to oryginal 87-100MHz. I'd be grateful if somebody could post a picture how the coils should be wound? Traces of original winding are visible in HF part, but I'm not sure, how it should look like in the oscillator part. 

I'm also not sure, if coils antenna->cathode are original, as there's definitely some bad soldering there.

Regards, 

Piotr
