Thank you all very much for your comments. I think my son is looking forward to creating a few 'heaters' while playing with a filament power supply.
The caution of verifying the 6.0 volt max limit has been noted.

Subject: [Boatanchors] Question for Eimac 4-65A Tube
My son and I have a question regarding firing up the filament of a 4-65A tube with no connection to the grid or plate (and no plate cap heat sink, either): If we light up the filament and leave it glowing for a long time, is there any danger to the tube? It would be akin to using it as a nightlight (which we are not). By a 'long time', let's say 5 hours.
Thanks in advance for any comments.
