Thanks for the responses. I had already found the speaker to be bad and was testing with an 8 ohm speaker (close enough for testing). The original had pretty much dry rotted and tested infinite ohms.

I found one of my problems to be my power supply, which was inducing the hum. Once I cleaned up the power, the radio is mostly working. There is some static while adjusting volume so Ill attempt to clean the volume/power switch.

I found a vendor for original type speakers which use the original mounting bracket.
