Power Triode Tubes

power tube heaters from 4x AA battery?

Is it alright to do this? I am experimenting with a single subminiature triode tube, would it be alright to power the heater from 4x AA batteries for 6v DC output and have the single heater in series with this?
Yes I can find some D cells to use, just no holder for them >.< Is there anything special I should know about how to wire it up? The batteries straight into the heater in series wont kill it will it? Should I have some resistor in parallel with it?

Ya!

it wont last very long. if it is a quick job, it will do.
