Many times the capacitors are bad and could be shorted. Usually the buffer capacitors around the vibrator need to be replaced. They keep the contacts of the vibrator from arcing when the make and break.
The electrolytic capacitors in the power supply are also good candidates for replacement. This is evident by a loud hum.
From there you get into the tubes themselves possibly or other capacitors in the radio circuits.
