Hi all, resurrecting this thread on my 37-116 that I started around 10 years ago. I finally got around to refinishing the cabinet after putting it off for so long. Ran out of good weather last fall so will resume soon. I drug the chassis out that I finished way back when to give it a try. What I found was the oscillator alignment for the AM broadcast bad doesn’t track well. I originally thought the replacement dial was off somewhat from the original but it’s too much now. I can get the alignment at the high end for 1500kc and the low end at 580kc spot on per instructions but when I tune in a local station at 830kc it comes in at well over 900kc. A station at 1060 is similarly way off. All this was with AFC turned off. I hate to mess with the mica caps but am considering replacing a few in the osc circuit with silver micas. I know I will need to realign the oscillator on all 5 bands if I do!
