Marantz 2230 Dial light replacement
I found that the easiest way to get at these dial lights was to remove the front panel and then the Plastic Dial and diffuser Velum.. You have to remove one screw that is beneath the Signal Strength meter and then carefully pull the plastic dial and diffuser away from the light panel. The Fuse lights are then very easily accessed for removal and replacement. Once they are replaced, the dial and velum can be put back in place using a touch of glue to secure them. Replace the screw under the meter and it is done.
