Ge 7-2660d

[RadioTVNut00]

Hello. I have a GE 7-2660D AM-FM radio that I bought at an antique mall. This morning, when I unplugged a pair of headphones, the radio lost sound. Now, I can't get it to emit any sound through either the built-in speaker or headphones. It does the same thing on both AC and batteries. I notice when I plug it in, I can hear the power transformer hum. Would anyone know what is wrong? Thank you
