Louxwe, you pull the rectifier tube and turn the radio on. Measure one plate to ground and then the other with your meter set to some high voltage A/C. You can also measure the filament voltage on that tube base to make sure it is in speck on a low voltage A/c. Be careful, there are some really high voltages off the plates to chassis. You can also do just a resistance measurements with the radio unplugged. Report back.
