To The group, I am, by far, not very learned in this field, BUT!
I think it the duty of the "more" learned in this group to help this guy by
not holding back and explain what he needs to do so he doesn't damage any
more transformers with this rotary gap!
Please do not ignore this post, HELP THE MAN! Isn't what this group is all
about.
