Unfortunately, he can't legally sell such a model in the US.  There's an 
FCC rule that the gain of an amateur service amplifier can't exceed 16 
dB.  Of course, it is permissible for a licensed amateur to modify a 
commercial amplifier for his own use, as long as it meets 
purity/stability standards.
