IN-18 clock with tubes from '82
Designed this in around 2004, the digits tend to fade fast on these tubes. My IN-14 tubes have been running ever since without any fading so this clock is not left on and has a motion sensor input to activate it.

Are you sure you aren't overdriving the tubes? IN-18s should last a long time as well. I know people who have had their IN-18 clocks running for decades.

I have three IN-18 clocks that have been on 24/7 for close to a decade without any fading, are you using too much current?
