In point of fact, since the typical antenna system on 137 kHz has a gain of -25 to-40 dBi (note the minus sign!!!), a 1 KW out amplifier is quite reasonable!

N6LF published an excellent tutorial on how to determine the efficiency of short antennas for these bands in QEX a year or two ago. My guess is it that it's also on his website. He puts most of his published articles on his website.
