The rest of the transceiver industry (other than you) apparently
thinks tube embedded HF transceivers are quite obsolete for a wide
variety of reasons. Else they would be manufacturing and selling them.
Even ham magazines print mostly solid state articles using modern
solid state parts, which is right since hams should learn to use
modern technology. When they do print a tube article it's usually
described as nostalgia.

Except the Russians. They were still using tube gear in their military
back in the mid 80s. Not susecptible to EMP (electromagnetic pulse)
from a nuke going off. They may STILL be using tubes...I'm out of the
loop since leaving the military in the late 80s...

Probably one reason there aren't more tube projects in QST, etc. is that
nobody is left who wants to learn an "obsolete" technology and the old
timers aren't going to bother writing about them because all they would
hear is bitching about how someone wrote an article on old technology
and wasted the pages in QST, etc. Just a guess.
