Hi Jeep:

I am responding from a dark hole - guessing. A shot in the dark, so to
speak.

I am guessing that the 6CL6 was converted to a class A stage for use with
the ssb adapter. The basis for this is my vague recollection from an early
Single Side Band ARRL publication by Father Morrison, who was a teacher of
one of my friends. He converted a Viking II for use with a Central
Electronics 10A sideband rig and basically did the same thing to a driver
stage (maybe a 6AQ5), using it as a class A stage.

So, what is good for the Viking II ought to be good vor the Valiant. I
think the article may have been in a 1955 or 1956 QST.

How is that for pulling out trivia from way back and applying it to a
different set of facts?
