Restoring a Vintage Zenith Table Top AM/FM Receiver from the '60s

摘要

Many electronics enthusiasts consider vacuum tubes and their bulky, hot, high-voltage circuitry artifacts from a bygone era. After all, you'd need a room packed with thousands of tube circuits to even approximate the computational power of a lowly Arduino microcontroller. However, discerning audiophiles, electric guitarists, and seasoned ham radio operators will tell you that tubes are still the best option for applications where tone and tolerance for abuse are paramount. There's just something about a vintage Fender guitar amp or a Mclntosh tube-type preamp that can't be matched by modern solid-state electronics. Even the simplest vintage and modern audio equipment built with vacuum tubes and point-to-point wiring can sell for thousands of dollars.
