I am all for replacement of factory speakers with better modern equivalents, and I do not mind people who re-guts their radios to be modern, but I would like to find a person who does electronics work on original radios and keeps them that way. I specifically have a number of late 60s early 70s GM radios which exhibit the usual problems of losing the channel's signal, and noise in the volume ****. I imagine they need cleaning in the potentiometers, and capacitor replacement. Is there a place known that does these things and has a reputable reputation?

 

This is the guy that done my AM FM for my W-30. I was VERY pleased with the work. http://fredsclassicradios.com/

 

Not that these pictures show what the guts look like but this is how I got them back. I took a cover off each when I got them back and they were just as clean on the inside.
