This is a really nice electronic 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 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 like Lowes*. 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.
* No, I don't own stock in Lowes or receive payment from them. It's quite the contrary,
in fact; I've spent thousands there in the last 20 years.
