28- After 24 hours of wait, clean the glass around the HV hole with acetone
liquid and retrieve the cleaned HV cup :
29- slowly put a CONTINUOUS fresh silicon paste all around the HV hole on the
bare tube :
30- Now press the HV cup anchors within the HV hole so the silicon paste is
moving all around the HV cup circular edge :
Take care: the HV lead wire output must be in the same
orientation as the original tube assembly had !
31- Use some large adhesive tape to fix the HV lead in stable position and let
the assembly to dry for a complete WEEK :
32- After a week of wait, turn the assembly upside down and cut the silicon
excess on the tube face using a cutter :
Cut the surrounding excess two times : one with cutter aside the tube face,
second time with cutter perpendicular to the tube face (using the aluminium
belt/holder as a ruler).
33- Once done, remove the silicon cord this way :
34- Once done, clean the tube face from silicon trace using acetone liquid :
The tube face should look this clean :
35- Then you can continue with the other tubes of the set (if any !) :
36- At the end of the set, you should got three brand new tubes ready to be
assembled to their respective LC tank/housing :
