Hi Nick, I was quite surprised by the lifespan on the IN-13 tube.. someone did a forensic laboratory analysis https://www.saltechips.com/lab/the-shine-experiment/ and found if the tube was on continuously, it would take 14.7 years to reduce in brightness by 30% from new. The Issue with the IN-13 is they poison very quickly, if they display a static level for a week or so it is enough to poison them. However on the spectrum analyser they will never stay at a fixed point, so I'm not thinking that the lifespan is going to be much of an issue.
