[Boatanchors] RE: Hii FI amp as speech amp - Heathkit Preamp?

[Stevan A. White]

Why waste it on SSB?  This is ripe for AM!  If you'd ever heard an older 
well maintained, well tuned tube-type broadcast transmitter passing 14 
or 15 kHz high fidelity audio you'd never want to go back.  I suppose 
that's why some folks refer to AM as "Angel Music."
