Bought a defective film variable capacitor and thought we'd tear it down and see what's going on inside. I said the insulators are not mylar, but now I'm thinking they just might be.
We'll take apart this increasingly rare 0–350 pF film variable capacitor to reveal how it works. We can see the inner construction—silver-plated plates, spacers, trimmers, and the mechanical design that controls capacitance, while also uncovering why this particular unit failed. If you’re into DIY electronics, crystal radios, vintage components, or just love learning how technology works from the inside out, you’ll enjoy this hands-on exploration of a classic capacitor design. Perfect for electronics hobbyists, tinkerers, and experimenters who like to see what makes their gear tick!
