A few things you may want to collect and store in case an EMP hits your area and fries all modern electronics:
Old fashioned vacuum tube equipment. You can find vacuum tube radios at yard sales, swap meets and on eBay. Take them to a musical instrument amplifier repair shop to get them fixed (A lot of musicians still prefer tube amps).
Old fashioned crystal radios. They don't need batteries! You could put the components in a box, unassembled, then put them together after the EMP.
