Timmy, just for shits & grins, could you please post a photo of the device you are speaking of? I'm kinda curious about this.
Ya know, if ya crank that heater voltage to about 8 volts for an hour, and then let it cool, and then check that red gun again at 6 volts, you should have a good idea if it will hold up for a while.
But then, if the booster you speak of does indeed correct only one gun, then perhaps that's the way to go. Of course, the rest of us want to acquire one of those as well!!
