Does ANYONE have a cheat-sheet of all of the pot-adjustments for the Midland 79-290 radio?

I need the locations all of the balanced modulator adjustments, as well as the main frequency reference adjustments and all the rest. My VR's are NOT MARKED on the board, so a pictorial might help as well --- anyone?

Thanks!

    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
