Bill,

Yes, I've "homebrewed" quite a few of non-QRP transmitters.  Back in my
undergraduate days, we had a carrier-current AM broadcast station on campus.  It
required individual transmitters in each dorm that were coupled into the 120/240
V wiring.  All of the transmitters were homebrew.  The two most common types
were a single 6146 modulated by a pair of 6L6s (running about 20 W out) or a
pair of 6146s modulated by a pair of KT-88s (running about 50 W).  In one dorm
quad we
had a master single 6146 transmitter feeding dual 6146s class-AB linear amps in
each dorm.

Someplace around my junk box is the remains of the last non-QRP rig I've built,
a 20 W 160 m amp that I used with my FT-817 (5 W with a low dipole on 160 was
just too frustrating!).
