I was checking out the wg4900 tube for my Q*Bert with my B&K 470 and did a clean and balance on the green and blue guns. Now I cannot get the meter to move when I try to set the G2 cutoff for either gun, but red will still move. Did I just kill those 2 guns or am I missing something? The instructions I have don't say what to do if any of the G2 cutoff adjustments have no effect. I've used my rejuvenator successfully before so I'm not sure what I did wrong. I grabbed another 4900 tube and you can set G2 cutoff so it's not looking like a problem with the rejuvenator. Thanks for any help.
