The roller-L tuned input for the tetrode is a bit easier to build than
the tuned inputs for the triode. If you need a roller-L, let me know. I
have a GE 25uH unit from WWII that uses solid silver #14 gauge wire, due
to a copper shortage during the war.

amen. 110w will drive the tetrode to about 10 out, or it will drive the
triode to about 2 out.
