Radioroslyn:  I did the experiment that you suggested - Yes, the Philco is oscillating - and I now have a replacement phenolic dial to complete the alignment.  

I think that I have discovered the problem:  When I moved from the States to Saguenay Québec in 2013, I unpacked all of my radios and verified that they worked.  They were then placed on shelves and only used if a visitor indicated that they would like to hear a particular radio playing.  The last time that happened was 5 years ago.  During the past 5 years, unbeknownst to me, almost every AM station in the province has converted to FM, or closed up shop.  There remain 4-5 very low powered stations, 6-8 hours away, used mostly for religious services, but that's it.  

I do not have an exterior antenna - and zoning will not permit one.  None of my radios can pull in a station, until the night time hours, and even then, the stations are faint.  I am in a virtual AM dead zone.  The Philco 60B may very well be working correctly, and I may have been spinning my wheels to no avail.  I have purchased an AM transmitter, off Ebay.  When it arrives, I'll connect to my stereo, and ascertain if I can receive its signal on the Philco.  Other than that, I do not know what else to do.  (No, I don't like the idea of adding bluetooth - I like to keep the sets original.). I'll let you know, if the transmitter is successful.  If it isn't, I'll be looking to you for more suggestions.  Please know that I am VERY appreciative of your responses.

I listen to old 78 rpm records, watch old black and white movies, and tune into online vintage radio programs.  The lack of high-fidelity, afforded by AM radio has never been a bother for me.  It saddens me to see the AM system vanish into obscurity.
