[QUOTE=Kevin Kuehn;3238202]Ok, so I'm not sure what would be different between the speaker being in the cabinet and out of the cabinet but with the speaker out of the cabinet the hum is non-existent, and I'm not sure if this would of affected it or not but I did replace the old broken speaker plug.

Partially because having the speaker on a baffle board allows it to reproduce the 60 hz frequency more efficiently. Without the cabinet the wave coming off the back of the cone partially cancels the wave off the front.

OK, well I'm going to try putting the speaker back into the cabinet and hook it up to the radio again and see if it still hums.

OK, so a little update, it was definitely the original speaker that was bad (bad humbucking coil) because I installed the speaker from the parts radio like this one, and it for sure was not humming whereas the original speaker that came with this radio did hum, in fact when I looked at the parts radio speaker and the original speaker for this radio, it actually looks like the original speaker was maybe missing its humbucking coil (it only had two wires coming out of the field coil whereas the parts speaker had 4 wires coming out of the field coil.):scratch2:

So now I can officially say that this radio is fixed, unfortunately though the parts radio's speaker was slightly smaller than the original speaker was, so I had to modify it slightly to make it fit in the cabinet. :thmbsp:
