Hello Listers!

I do not belive that solid state transformers cause mercury staining.  I 
think what has happened in this case is improper pumping.  If a lamp is 
not pumped correctly it will stain and using solid state may expedite the 
staining.  Why? Because SS tranies will run hotter.

What do you mean the glas or the transformer or both, as I realy cannot
understand what you are talking about.

The big clue here is seeing staining close to the electrodes.  If the 
electrodes are brought up to temp when the vacuum is too great, the 
impurities will settle in the tube.

Transco has published a really nice pumping routine.  A copy of this 
senario is available at www.lightwriters.com/nw   Anybody wanna see it 
posted here?

Jacob

Dear Jacob,
I realy don't think that that is the (your) problem. Look to my reply 
about the composition of the fluorescent powders and maybe that will help,
o r at least think about it as I noticed that is the real truth for your
staining when HF converters are involved. Again, I have never fully researched
this subject as I thought it was not neccessary as this problem only occured
when HF converters were involved, so for me it was totaly clear.
