G07, newly rebuilt. B+ won't stay in one place. Goes as high as ~121VDC, or as low as 88VDC. Picture is pretty good. Voltage changes on brighter or darker images. Darker images = higher voltages, and vice versa.

I was going to make my own, but wasn't sure which circuit breaker he uses.
Just put two alligator clips on some wire and solder the ends to a fuse holder. Not as good as a circuit breaker, but you can easily change the fuse.
And I'd put a fuse in there. The bulb might be enough of a load to pull down the B+...
