P.S. and my own comment on the OP ... and as others have hinted at. valve radio gear really is immune to EMP bursts that would just kill today's micro electronics.
"More immune", I think is a better description.
Properly designed solid state will be easily immune to EMP if it's in a metal case with attention paid to decoupling inputs and outputs. There's a good reason nobody's really bothering with EMP weapon research.
