The horizontal board is the Mother board.  I don't see how that can hum.

 

Yes you will see burn marks on the coating.  If the RS Boards and Speaker are removed the only other hum could be a coil coupler.  Unplug it.

 

If still humming, check for a short between Pickup roller and chassis ground.  G
