I've seen the ones with the weld problem!
If they will hold the low voltage (CW) position of the TL922, then I can
getter them.

If they have never been fired up, they MAY be gassey. I just removed a
pair from a TL922 that were new in the box. On was gassy at less than
500 volts. I'm not at home so I cant get you the date codes.
There was a run of them in the 80s that had the welds break where the
cone that holds the plate on the stem would break lose from the plate
itself and flop loose inside the tube.
I'm not sure of their date codes that had this problem.

Subject: [Amps] Eimac 3-500Z date codes
I know this information has appeared here, but I haven't been able to
find it. Which are the "bad" Eimac 3-500Z date codes?
I have a pair that appear to be unused that have the code 8240. Does
this mean they were manufactured on the 40th day of 1982?
