I found a neat handful of Audio-class vacuum tubes in a banged-up olden radio, going to attempt to create a Tube-amp using them.

Fun Fax: The vacuum tube found on the cover of the Foo fighter’s album “Echoes, silence, patience & grace” has a striking resemblance to the 6V6 beam-tetrode audio tube.
