1R - 1T

Watch out! These are TX Items. Part 4 is not a 'read-back' value. Loose or bad contacts are not detected. Look for extreme 2R-2T currents (no seesaw).

Electron beam is twisted a little bit during its path through the accelerator tube. It is possible that the 1T current influences GT and the 1R current influences the AB plane but this is not always the case.

Values only need to be changed after a gun replacement!

When gun filament is centered, values are near 0.
