    Default Possible to regas a Spectra 132 or 134? If so, how much?

    I have a friend who purchased a couple he-ne's that have some historical interest. One is a SP 132, the other is a SP 134 (he says; I haven't seen them).

    The tubes flash on and off. He says they have outgassed and need to be regassed.

    Is this possible? If so, who can do it and what's involved in time and shipping and money?

    Thanks for your help!

    dale harder or steve Robert’s. I just gave them each a 1000 liters of neon. Dale has direct experience repumping both.

    Not practical. Waaaaay cheaper to just replace the laser with modern He-Ne, and keep the old heads in a display cabinet (with cover off?).

    Both I and Dale have the isotopic neon and helium.

    Start with Dale and then call me if he cannot help you. Looking at a 132 picture, the advice of dropping in a new tube is a bit more appropriate, due to the way the soft mirror seals are sealed on a glass tube with the flat ends precision ground for alignment. I can't guarantee I can get them clean or on correctly. In other words, I could open the fill stem, process the cathode, and just refill. Not a great rebuild.
