Possible. It did have a '+' on one end of it, but I couldn't get a reading out of it with my meter in diode check mode so out it came. Seems this is gonna be the easiest resto ever...
Got a nice bright raster, and HV doesn't droop even with the brightness control at max. There is a slight blooming though, and I see some drive lines. I'll run through the horizontal setup procedure, purity and convergence, then throw some nice patterns up.
