Simple a Crow Bar or aka Polairity guard diode like a 1N4000 -1N4004  I had people give me the radio just for a 25  cent fix and $20.00 labor and I even had one the foil fried because some Golden Screwdriver tech, ( I laugh at these clowns ) decided to bypass the fuse being reversed power polairity , simple fix with the iron and a peice of wire jumpered ABT 3 inches viola working radio.
 
also a short in the radio on a 2M .  Heath short also blew up the cap I replaced. been there blew up that !.
 
anyway Smile on life is FUN !

Hi There,
 
There is a fuse that looks like a plain diode near the power input leads that is now more than likely blown....
 
How do I know this? ....... experience!
 
I don't know which part it is, my memory has failed me. 
One of the guys here will know!
