Hi, just saw Shane Speal’s feature article on the 1957 tube driven tremolo plans. Pretty cool! But frankly, high voltage stuff scares the bejeezus out of me… that and my brain can only handle super simple electronics circuits. Other wise it becomes a fog of confusion.
We love vintage plans, especially ones from the Eisenhower Era. Here’s another one to drool over and explore: a One-Tube cigar box amp! The plans were first published in Science and Mechanics, Feb. 1954. We’ve taken a scan of them, cleaned them up and put it all together in one downloadable .pdf file below.
