Lower Powered Tube Integrated for Studio/Shop?

The space sees 80% of use as an art/photo studio and 20% as a light use wood shop (mostly for picture framing) but some amount of dust gets generated. I was thinking something like a 20/30 wpc Jolida straight tube or hybrid thru a pair of Klipsch Heresys or Cornwalls might be good in this 14' x 24' shop but am wondering how much of a tube amp killer a bit of sawdust every once in awhile might tend to be.
Thanks.
