Are there any modifications to this radio to increase Modulation and AM & SSB power?

Well power mic's where invented for this very reason. Most of those early radio's shipped with 2.5 to 3 watts of power and 60% modulation.

If no pot exists then it is time to substitute hard jelly bean parts.

As old as that radio is I have to assume the caps could be as dry and your average spot in Death Valley.
 
Caps are fine, I have a TRC47 since 1976 . never a problem.

There is a tiny , very tiny pot you can adjust. It will get you up to 100 % modulation.
Power not so much

    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
