Well I've read a great deal on these forums about this amp and I have learn alot about it and made mine perform better and better.
I tuned the low and hi SWR inputs to the amp after learning what those adjustments under the driver tubes and the hi-low switch were for. Thanks for that info.
Still a question i have now is...Under the driver tubes there is another adjustment, a recessed tuning adjustment, not the one for the swrs. Just curious as to what this is.
Anybody know ?
 

If you mean the metal-body (usually) trimpot between the rear driver tube and the rear panel, facing down from the solder side of the driver pc board, that's the meter's sensitivity adjustment.

    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
