I've got a HeNe and everytime I touch the tube the output flickers, then shuts off. This only happens when I touch it. If I turn on the PSU (and if the HeNe successfully ignites) and leave it alone nothing happens, the output is stable. As soon as I touch the tube case it goes haywire.
This HeNe is dear to me and I would like to fix the problem if possible.
Does anyone know what causes this?
It's a melles griot 05-LHP-153 with a 1.7kV 1201-1 Uniphase PSU.
