Harman Kardon citation I faceplate decal,  Three piece decal or use the section needed. the brown color is a bit darker than the original. holes are cut for the knob shafts and switches. use soapy water to align. then spread from center outward with a credit card. This is the next best thing to restore your lettering. also the decal is clear between lettering not white.
trimming of decal might needed to fit around the  edges.
