Hello list members, My favourite surplus/junk store has a stack of new ceramic hydrogen thyratrons that were purchased as part of a box lot from the NZ Navy. The component markings are as follows: EG&G HY-11T MADE IN U.S.A. 9122 MFR 25506 Does anyone have pin-outs or data-sheets for these tubes? I've looked in all the usual places but haven't found any references. Thanks in advance for your help, Gavin Hubbard
