If you run tube filiments off DC the filiment life will deteriorate due to filimemt streatching.
Halacrafters made a radio that ran on 67.5 VDC and 110 VAC.

Here's a tube tutorial that looks pretty good for a start.  Then google "vacuum tube tutorial" if you want more.

Lot's of websites on tube radios and amplifiers available.  And lots of tubes still around.

Good luck.
