i have a b&k 490 that sometimes i get a "FOCUS OK" light to come on on some tubes and not on others, but they all look ok???
is the focus on rejuv really the focus part? i thought that the focus was really only controlled by the fly?
also, if testing a tube and the light doesn't come on, is it suppose to be blurry and unrepairable as the manual says?
kinda confused on this one, can someone explain please?
