>> And still works! Built to withstand an atomic bombardment. Except for the EMP. It'll theoretically render such devices nice looking, well-built scrap.
The old completely vacuum-tube-based, discrete component oscilloscope from back in the day may actually survive such an event if it's outside the blast radius but still reasonably sheltered; and you are also outside lethal fallout zones, or can shelter and survive in radioactivity-safe places for a long time. Stock up on quality-made (e.g., Tektronix, Hewlett Packard) tube and cold-cathode-based test equipment (VTVM, oscilloscope, etc.) as well as quality radios and transceivers. Hopefully they will continue to serve as interesting artifacts of a time gone by, but if something were to go sideways in our world, they could potentially come in very handy.
