The green tube was low, (0.2 on my B&K 467). The other 2 were 1.2 and
1.4, so I rejuvenated the green and it came up to 1.6 on the first try.
Picture looks good except for some flaring that can be controlled by
turning the picture control down. Hopefully it will last for the
customer. I would like to know why the IK blanking did not kick in with
this weak tube. Thanks for all the replies.

Surprisingly it comes on almost right away (within seconds). I wonder
why the IK blanking circuit is not working in this case.

Pinkish picture = weak green CRT or low green drive
I bet the set takes 60 seconds to come out of IK blanking from a cold
start!
