For me FM is crucial in these tube radios, so ensuring that it works perfectly is paramount. This one had no component problems, but ... someone has been in here with a screwdriver. Yes, it happens a lot. Reception fails or is unsatisfactory, and some smart Alec thinks it is a good idea to turn any screw that a screwdriver will fit into. The usual victims are the IF transformers, and usually the ones on top, which is the case here.
Never mind. It's an easy fix.
Hope you enjoy the video.
