I remember in the days of vacuum tube HV rectifiers, this would happen when the rect tube was weak...but in this mostly solid state scope, I didn't think that would be the issue. I'll put my nose to the ground at swapmeets (and here!) for a spare CRT, just in case.
The emission I'm talking about is that of the CRT's cathode, not something in the power system.
