[Hammarlund] Old Hammarlunds - modifications.

Overhead is very overblown in the audio world. You dont need 16W capability 
at low distortion to listen comfortably at 2W with only marginally less 
distortion.

The military and commercial enviroment some of those sets were initially 
used in might have needed that much power.

We are listening to AM, not a symphony or some wailing opera screecher.

Hook up an audio wattmeter and set to 2W and then switch to a Hallicrafters 
12" or R-42 speaker....I bet you will turn the volume down.
