Has anyone tried to rejuvenate 01A tubes using a battery set to apply voltage to the filaments? I was reading on a different, and inferior, forum that 15 minutes or so at about 6.3 volts can help marginal tubes.

I have also read that the process doesn't work as well on some manufacturers. My Freed Eismann NR-6 has a set of WARDS 01a tubes that measure in the low acceptable to low marginal range on my Triplett 2314.

So, the idea was to apply 6.3 measured at the filament pins with no other voltage on the set. Can someone explain why this is a horrible idea?

Don't worry, it is just a mental exercise.
