Nice piece of work. I have to think that drawing the schematics for the
thing required a drafting board, a set of templates and a sharp pencil. No
CAD tools in those days.
The alignment procedure "as noted in the manual" would keep a tech busy for
hours.
Look at all those tubes! One is even called the magic eye. Besides
broadcast, medium wave and short wave - you get a nice heater for the winter.
$10 seems a steal except you have to drive to Dayton to pick it up!
