Ooops, sorry Gregebert, I'm not experienced with google groups and I didn't know the difference between reply to group vs. reply to author. I'm going to repeat my question so it's group visible: Basically I was wondering for multiplexed vs direct drive, if given the same voltage and current

>From what I've read, the peak current is what leads to tube wearout, and the effect is exponential: double the current, and the lifetime will be less than half the normal expectancy. So when a tube is pulsed, such as with multiplexing, the perceived brightness will always be lower compared to
