Try taking the power switch section of the switch off the combo switch and shoot some WD-40 into the power switch and work the power switch lever back and forth a few times and then flush the switch out with contact cleaner and measure the switch with a continuity tester on your digital multimeter in the "on" and "off" position, in the on position it should beep at you, in the off position it should measure open.
More than likely your power switch's contacts had arced and welded themselves in the off position, spraying the WD-40 into the switch and working it back and forth will work the contacts free, I've done that before on a 1936 Philco Model 116B radio I'm working on restoring which had the same issue, except in my case I couldn't get the radio to turn off with the power switch rather than like yours where you couldn't get it to turn on.
Hope this helps.
