Start with Telefunken's work for the Nazi's to make electromechanical means to amplify and transmit "the hypnotism in the Führers voice" which was completed in time for the 1936 Olympics. Continue with the observation that key technologies and people where "paperclipped" to the US where they ended up in a project called MK Ultra...

All about a specific kind of fidelity...

My guess is that CD's are not quite EMP proof, put one in the microwave.

I don't believe the vinyl has sufficient conductivity to flashover in the event of a pulse, so I believe they would be good.

I suspect however, that any 78 player which was in an unwound condition during the event would find the main spring is dead due to loop trapping, whereas the wound ones would be playable until the spring wound down, the crank assembly would probably be welded frozen.

Luckily, my weight driven wooden gear clock would still be able to tell time accurately. The mantle clock... DOA..

Not the point, Scott. The MIG 25 was EMP proofed by using tubes instead of solid state. A Russian realization of a TRUE advantage over the West. Brilliant concept.

What are the limitations of semiconductors to an EMP?

EMP hardening for semiconductors would be too heavy for a fighter plane.

Thanks,
Chris
