Hello, Working on a Philco 89. I kept checking my work as I went along and all was well. I am now finished (so I thought) but have noticed I can not pickup anything below about 900 kc on the AM band. I think the oscillator stops running as I don't hear the squeal on another radio. Above that all is good. I thought I narrowed it down to the 36 tube being picky. I found one that worked through the whole range. Now that it is ready to go back in the cabinet I found I have lost reception below 850 kc. Any idea what might be causing this. I have another 89 and the 36 tubes I have all work in that one.
Thank you,
Dan
