fluctuating power -- tube or power supply?

samedi 28 février 2015

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.)
