This is a really nice electronic
schematic symbols chart that will come in handy for hobbyists who work with vintage
electronic equipment. Not only does it have component symbols that a modern chart
(this appeared in a 1942 issue of Radio-Craft magazine) would not likely
contain, but it has three-dimensional sketches of each device. For example, vacuum
tube symbols show the tube outline, its socket configuration, and the pinout. If
you get nostalgic for some of these old parts, some of them like the
knife blade switch and
ceramic light socket can be
bought a many hardware stores or online. It's too bad the chart is not in color
because it would make a nice picture to frame for a decoration. If anyone with an
artistic bent feels compelled to colorize it and send it to me, I'll be glad to
make it available to visitors. If you use Visio or any of the Microsoft Office software,
you might benefit from my custom
