Don't worry about the shocks.... They're good for-ya- I got a good one once off some 17"
tube set I needed to adjust something and stuck my hand in there, and I watched a spark
jump from the picture tube to my hand on one side, and from the other side to the cabinet.
It cooked the skin and was a hard spot on both sides for months.... And dammit I'm still
here.... And stayed there for the rest of the day, and kept going back day after day...

Just remember to keep only one hand in there, and no path through you to ground....
So be careful what you wear, how you stand, and what you stand on...
No kneeling on cement floors...... Rubber mat maybe two if on cement.

It sure sounds like the picture tube does not have a proper bias setup... Overdrive
all the time.... Something is wrong there.... Have you gone over the voltages...?
At the picture tube pins...?

Lets check


Pin 3 I have 315V
pin 6 should be around 200V
pin 7 600V

What do you get....?

Anyone have good numbers for both sides of the pots on the screen controls...?

Anyone have ideas....? Worry about this now, or not....?

Added second picture with question Kine bias pot good...?
