Make sure the alarm set button is pushed all the way!

Nope, I already checked that, in fact that's what I thought it was at first, but when I hit the button to turn it off the humming coninued and it was coming out the speaker (kind of sounded like the way Sony did their alarm for their Digimatic alarm clocks for years where they would produce a 60 Hz hum out of the speaker for the alarm buzzer, rather than a mechanical buzzer).

The funny thing is that when I test the old capacitor's leads they test normal, no shorts or anything, charge up to over 15 Megaohms and then slowly discharge like they're supposed to.

I might put it back together and see if it was maybe just a fluke.

EDIT: just put it back together and tried it out again, and it seems that now the power supply cap is completely shot as now its humming in all 3 different power settings not just the alarm/radio mode. So it seems I will definitely have to replace the power supply caps in this radio, as well as the paper caps in there.
