I have a Model 90 lowboy that until recently was working very well. It was recapped, retubed, and aligned, etc. - the extent of my technical expertise. One day it became almost totally deaf, receiving only the one, close station. I don't see anything obviously wrong. What is odd is if I connect a jumper from the antenna connection to the oscillator tube anode (I think that's the tube), it receives pretty well. Probably not as good as it should if the earlier stages worked, but decent reception. While this "fix" solves my issue, my OCD wants to make it correct. Any suggestions as to where to look? My concern is one of coils failed and that's above my pay grade, plus the challenge of rewinding or finding a replacement.

Any advice would be appreciated.
