Hi Marc

Thanks for your informative comments.  There is some  bluish colouring on
the tubes but no flaking yet. This is after approximately 30 accumulated
minutes of operation. Most runs are limited to about 10 - 15 seconds because
I have only one NST and want to keep it healthy (champagne appetite and beer
pocket book).  You can see a little of this discolouring in the jpeg
picture. I am still coming back from the moon over its improvement over the
single static gap.
