OK so I had ordered a couple of new Vertical Output/Oscillator Tubes for the TV because I wanted to see if that would make a difference in the operation of the vertical operation, and I installed a new 6LU8 tube into the TV and the TV did something it never did before which was that some of the components on the sweep section board started arcing against each other and then the Horizontal Output Tube was arcing between the grid cap and the High Voltage Cage.
The TV does have a fair amount of dirt and grime built up on the circuit boards themselves but the inside of the HV cage and the Picture tube itself are spotless which is why I said I thought it might of been a low hours set but the dirt and grime buildup on the boards was just from the fact that the TV was stored in the previous owner's garage for many years.
Would the dirt and grime buildup on the circuit board be the possible cause for some of the arcing I'm seeing inside the TV?
