Cool... but those are amplififers with ridiculous frequency responses! 10Khz 
to 100Mhz? Wow! I'm sure the prices for those units would be several times 
that of a sub-Kw rack-mountable MW box!

You'd best make absolutely sure your input is absolutely pure... and there's 
no chance of any feedback, or you'll be (literally) filling the spectrum from 
audio up thru VHF!
