Forrest Mims did a bunch of interesting hand drawings like that back then but I don’t recall the specific book or image you are thinking of. I’m curious to see if you find it - it sounds up my alley too.
Thanks! A bit different, but definitely worth exploring more.
Here's a pretty close approximation of the illustrations: https://www.etsy.com/listing/4319242515/testors-robot-plasti...
You must be thinking of The Forrest Mims Engineer's Notebook or his Engineer's Mini-Notebook or Getting Started in Electronics.
The Engineer's Notebook is still in print:

If you download the free Kindle sample, it has some of the illustrations, but mostly just individual components.
This Reddit post has a couple of pages from Getting Started:
