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.
