Re: Valve testers & 'soak' testing.
In the case of what Tek and others did, it's a process to weed out infant mortalities. New valves with a defect which limits them to a short life, but which doesn't spoil the parameters in the beginning, say like a poor seal on a pin, or one not outgassed properly.
Much of what they did wasn't selecting valves for better parametric performance, just improving the confidence they could have in their longevity.
