Thanks to Elmer and Cesar, leaks have been improved.
In the recent past, the leak-up rate has been ~ 10 mTorr / minute.
Today I got ~ 0.5 mTorr/min, 20 better.
This may affect some recipes (Ar) but not likely others if O2 is part of the recipe.
New RF is much better than the old,   no warmup issues, seems more stable. I vote for making it permanent.
