A guess?
If you see no power out on a meter; then it could be the driver. If there is a little power out; then I would suspect the final. That has been my experience. I'm not familiar with this radio or its particular failure points, but what I said is typical for most radio outputs...Maybe there is a particular failure point for this radio...Dunno...
 
Take the final out and do a diode test on the multimeter to start with. That would be a quick n' dirty test to see if you have a problem.

    Hello gentlemen and Ladies. I have the dreaded RCI-2990 receive issue where my radio gets distorted when people get close to my location. I found the C90 Capacitor, but I can not for the life of me find the C89 capacitor. Can or does anyone have a picture of the exact location of C89 ? Thank you in advance, Wes
