Tracy, let's just get back to the basics, do you have an ohm meter? If so, radio unplugged and the speaker plug off the back of the chassis, measure the resistance between the plug held in your hand. According the schematic attached as a link, there are 3 lines going to the speaker. Set you meter to perhaps 10K. All three lines should check the field coil and output transformer primary. If the measurements do this (the meter dips down to about 0), they are good. Report back please.
