Topband: Linear amp

Page 6 states, when the amplifier is in the Single Sideband mode, SSB or CW, 
the amplifier is in the linear mode and delivers 1200+ peak to the antenna.

Tuned or unturned,  if  the toroids or tuned circuits  are running hot, then 
too much RF is not going to the antenna, a re-think of  circuit components, 
and design is a good idea.

Am signing off  the thread for now. Thanks to everyone for the input.
