Another update:
Cleaned the band switch.
Now the 31M band is working.
It's too late in the evening to try the 25, 19 and 16M bands.
And, best of all - AM is working! Very weak - but it is bringing in some AM stations!
I'm frankly surprised AM works at all, as I measured the DC resistance of the AM oscillator coil primary and secondary prior to trying it out again. The primary is supposed to be 2.5 ohms - it measures just over 5 ohms. And the secondary, which is supposed to be 4.5 ohms, measures over 7.
???
I'll try it out again tomorrow as soon as I get home from work, while there is still enough daylight to receive something on the higher SW bands, and see what happens.
