There seems to be a lot of problems lately about whether a thyratron is functioning correctly. Some of the more resent posts.

I feel reasonably sure that with a little digging I could find a lot more more like these.
My question is, can thyratrons be tested by disconnecting the grid connections from the tube and substituting a Variac or equal between the cathode and the grid (through an isolation transformer of course)? The tubes are quite expensive and there is no longer the corner drug store that one can take the tubes to for test (not that one originally could!).
We have available people that are either experts on this subject or very knowledgeable that have chimed in but I sense a lot of frustration by owners. Is it possible for someone with the right equipment, transformers, scopes, etc, that could rig a test setup where a tube could be shipped for testing? I would do it, but all I have is the scope and voltmeters. I have no working knowledge of thyratrons.
Does Monarch have test manuals for these machines that outline in detail how each circuit works and how to trouble shoot it?
