Did you, as a service guy, actually fill out that table ??

I never really was involved in 'consumer' valve electronics; but in times-past I filled in plenty of "Factory return" forms for Eitel-McCulloch [Eimac] 4CX350 valves that had been run for 1000 hours 'sweat testing' with a two-tone SSB test at maximum rated limits; this was part of my QA procedure on the HF linear-amops I was producing, and I'd label the return-forms something like "This is not a failure, just tell me how healthy these tubes are?"
They invariably came back with a report saying "these are still within original production tolerance" which was reassuring.
