I work on pinball machines, and the Gottleib machines loved using their VFD displays for scores.
Dimming is a problem on many of these. There is a simple trick we'd do. We find the heater connections on the displays and connect them to a DC voltage a bit higher than normal, for just a two seconds. You want the filaments to get a similar color to a tube filament. This usually helps to greatly brighten the unit up. However...we get similar rejuvination letting them run for a couple hours. If its a clock radio, its already running all the time..so you may need to check your supply voltages. Sent from my Samsung Intercept with Tapatalk
