I am a bit afraid of all those inexpensive displays made in PRC, the seller often doesn't know what he is selling, the specs are wrong or trunked, and I don't know their behavior with 300V DC or more...
Well, I ran a few of my IN-1, I had to run a couple of them at 4mA 180V and the black marks disappears completely after 4h. I can reduce to 150V 2mA and still have a good glow. those tubes are very nice with the "normal" 5, much better than the IN-4. should be nice on a 6 digit clock with a decatron for tenths of a second.
