Rather suddenly my power has dropped and is very uneven. Engraving starts out very light (almost no power) but usually picks up power after a minute or two. It then can fluctuate. This is with a newish (less than 60 days) RECI S2 tube. (The new 'stable" series tubes.) The Shenhui tech in China seems to think it has lost gas. Can a tube that has lost too much gas SOMETIMES has much more power than at other times? Or is it more likely the power supply?

(I have a spare RECI power supply in Customs that should come to me sometime next week. So I am stuck with guesses for the moment.)
