I sure do, and when you drove that in to a Johnson Killowatt, it was and
still is fantastic!!!
I liked my valiant better on CW than my apachee, so I used the apachee and
sb10 as the vfo and sideband generator.  I took the sb10 output and drove
the valiant's amplifier with it.
That gave me around 300 watts class input for the amplifier.  With 6146
tubes and a class a-b-1 amplifier, who knows what my PEP was.
Probably about the same 300 watts.
You couldn't move 5 KHZ with out adjusting something.
All I had to dip the final was my ear on the valiant's case.

Guess there wasn't a lot of audio processing going on.  Phasing out the
unwanted sideband and nulling the carrier, leaving the audio pretty
untouched.  Remember how good a Johnson Ranger and D104 sounded?
