Sure, but a breadboard on an old radio is like putting a glass jar in a sandstorm—great for quick checks, but if you want the thing humming cleanly, you’ll solder it up. Start with the basic schematic, pull the right chips—preferably the ones I still have in my junk drawer—then hand‑solder the main loop. If you need to tweak a couple of components first, a breadboard is fine, but the final version should be glued together. And about that donut—bring it over, but don’t expect me to split it with you.
