I now have in my possession 3 used pmt's, (Ebay purchase). They are Hamamatsu R1306-02's. The calibration/test sticker on them bears the date of September 1981.
That means they're 20 years old. Are they still likely to be good?

Re: Do PMT's "wear out"?
PMT's never wear out. They can readily be damaged if connected to voltage in regular light. Other than this blunder, and assuming they do not develop a vacuum leak, or have elements short out due to rough high G handling, they are just not subject to failure by age or even years of actual use in electrical gear.
