37-690 band 2 troubles
#1

My father picked up a 37-690 that has been restored just recently. The only major problem is band 2 does not work. My father talked to the guy that rebuilt it and he claims most if not all 37-690's have bad oscillator coils causing band 2 to to be inoperative. He also claims replacements are not available and repairing the existing coil is not an option. Does this sound correct? My father has a spare 37-690 for parts, possible good oscillator coil? He also has 3 37-116's do they use the same oscillator coils?

I also don't think this guy spent much time aligning the radio either as it tunes kind of funny almost like anti AFC. This is with magnetic tuning off.
Looks like aligning one of these beasts will be a pain in the neck.

If the oscillator coil is at fault and a replacement is available it looks like fun. My father was a radio repair man in the mid to late 40's then worked as a radio engineer at a local AM/FM station for 45 years. Trouble is he is 84 years old so it looks like I'm going to be the man for the job.

Thanks for your time
