[TenTec] KPA 500

[Ron Castro]

I talked to a manufacturer who makes commercial SS amplifiers, and they do 
have one that is bullet-proof, auto-tune for 1.5 MHz to 30 MHz, 1.5 kW which 
is designed for military and short-wave broadcast.  It's rack mount and only 
a few rack-units. ...and it only costs $30,000!  Wow, such a deal!
