Yesterday my TK-790 suddenly stopped giving me audio output, The radio is configured for both an external speaker and a PA speaker, both of which are no longer working. At the time i was connecting the wires of the PA output to a small 20W audio amplifier and couldn't figure out why i wasn't getting any output. I disconnected everything and checked the audio and nothing, The radio did have audio beforehand. Is it safe to assume i fried the Audio amp or is there something stupid i'm looking right over?

Why would you hook the PA to an amplifier??(it is already amplified)
You have blown your amp,it has a floating output and you cannot ground speaker low.
