They're fairly quiet sounds, recording them is indeed not too easy unless you already have a proper portable recorder like the ones from Zoom or Roland.
If you don't need them urgently, i can make a few tries. I tried with a contact microphone and i instantly run into two problems: RF clicks from the starter, and inductively coupled hum from the ballast. So the only option would be to use a well shielded condenser/electret microphone, because a dynamic will gladly pick up the magnetic field from the ballast. I do have one, but i need to set up everything outside of the room with my computer. But that's exactly where all my lighting stuff is.
I don't have any EOL tubes. I can make them plink a few times if i lower the input voltage to 190v or so, but they start annoyingly easy.
