Yes, I'd meant to say "coil", thanks for the correction
I've got a Hickok scope that would fit the bill, just needing a recap....something that I've been meaning to do.....actually was going to be my next project after this one.
Just so I'm following correctly, a misadjustment in this would potentially cause cathode resistor heating......is it likely that the resistors that were weak to begin with? I'm assuming the heating would cause failure, if the set were operated long enough, and the heating is being caused by an overload.
You'll need a little patience with me at this stage, as I'm trying to understand what is happening, electrically.
