RE: Testing WE 287A and 394A mercury vapor thyratrons

Use the tester set for something like an 866, and test that way. The filaments on the 287A are a bit stiff, I think something like 2.5V @ 6.25A (I forget offhand) so might require some adjustment to the filament supply of the tester to get the filament voltage up to spec for testing.
