I’m looking at restoring a Yaesu FTDX 401. The radio is untouched and belongs to the original owner. He has had it in storage for years. In addition to reforming the caps, repairs, alignment and clean up, lots of cleanup, I’d like to paint the chassis. This one is so faded I can’t tell if it is black or grey. Does anyone know what color the chassis were on that radio from the factory? Has anyone restored one of these beauties? Any dos and don’ts. Final replacement issues etc?
