That's exactly what that 80 was doing in my 118H when I got it and on my tester. Didn't even have to watch the video to know what you were talking about! Sadly, my current tester does not have a gas test like my other one did, but that 80 was doing that same bit at the regular voltage and it was causing the transformer on the radio to overheat.

Mine all do have gas test(ers). I really would not count on them. better to look for the purple glow and low or what seems to be really good performance (be suspicious if the meter pegs as mentioned).
