[R-390] removing a tube from a tight space

[Larry H]

Hi all, I'm with Jacques on this.  I like the rubber tipped forceps like
the one he mentioned.  I see them once in a while on the internet.  I like
them because I can remove all the tubes and tube shields in an R-390A
easily.  And, I can reinstall them also, especially beneficial when they
are hot.

Regards, Larry
