Removed the top cover last night and found all those solder points jammed really close together,so now I will remove the bottom cover and see how it will be to get the resistor & diode out once de-soldered. Right now it doesn't look very promising. I use to work for a electronics company and see the girls solder circuit boards under magnification and even microscopes but they have better manual dexterity than me. I was a maintenance man. I won't risk messing my radio up if I don't like what I see under my Big Lite Magnification on my bench. I'm definitely better with my welder than my soldering iron. LOL
