If you dont see the arcing you can use an insulated tube like
a paper towel tube to track the noise down. Works great
for me as I cant hear the hoz freq. Can find screeching parts
that way even if half deef..............
Your green is prob 1 of 3 things.
1) the green is the best tube.
2) the green is the worst tube & is bleeding.
3) G-2 too high on green.
Things can also need cleaning & the coolant is a common problem.
