If I remember my electronics, a solid state device usually fails in as a short circuit. Walk across a carpet and touch an antenna on a radio and ZAP it is a goner. Not quite an EMP but similar. Would a crystal type radio be able to get stations outside the EMP area? Might be worth looking into. I would think a radio stored in a metal cabinet would survive so spare electronic parts probably would also.
The big issue would be the hundreds of millions of electrical transformers that would be fried and replacing those would take years and years....every house and business has one or more...
