(conventional types)
1/ When Ec2 is greater than 330 V dc, Rg1 shall not exceed 0.5 MegΩ. When Ec2 is less than 330 V dc, Rg1 shall not exceed
1.5 MegΩ.
2/ The neck and base straightness shall be determined by the insertion of the tube neck in a cylinder 5 inches (127.00 mm) long
and 1.500 +.003, -.000 inches (38.10 +0.08, -0.00 mm) inside diameter. This cylinder should move freely between the
reference line and the base of the assembled tube.
3/ The raster shall overscan the tube face. The centerline of the raster shall be adjusted for best focus.
