Maybe run the heater off a separate filament transformer?
Was wondering if a green phosper tube's cathode and other guts could be a doner to rebuild a white phosper tube? Or would the cathode being briefly exposed to air ruin it? IIRC, cathodes have to be cooked when first in a vacuum, and you might not be able to do that again.
