Bob or anyone on group,
I readjusted G2 controls, that has stopped the green from blanking out and
the red from getting bright. I hear aloud pop as if the anode leads may be
arcing but can't find, tried waving my screwdriver near anode boots and
around flyback but wouldn't arc only pops maybe 2-3 times in a day.
Could this still be G2/focus control block?
Also I have jail bar lines on the left, suspect cap on B+ to Hor output.
Would you agree?
