With the upcoming solar maximum looming before us it is even more reason to build a vacuum tube amplifier for music reproduction. Vacuum tubes being impervious to EMP, as opposed to semiconductor junctions, would continue to function.

Of course unless you live in a Faraday cage, you will also need a source for your music. Ah ha! Vinyl records! But with the power grid down you will need a power source for all of this.

You are going to need lots of batteries, a recharging source such as wind or water generator, solar panels, etc., and a vacuum tube power inverter.

Nevermind....

And when the entire world power grid collapses, then civilzation will collapse right after it. You will need a large supply of food and weapons to defend yourself. Plus the food wil eventually run out, so you will also need a large defendable plot of land to grow food and raise animals. Inbreeding could become an issue if you are limited to your own family, so you will need to include other individuals to breed a replacement society.


Oh, and stiffening caps for the car stereo.


It is going to be a lot of work.

EMP will not kill all solid state. Equipment that is shielded will be fine. If its in a cave, on a submarine, or in a screen room, it has a good chance of surviving. For that matter any serious ssurvivoialist should be burying there CB radio in the ground. (Best place for it anyway).:)

If you ever get a chance to check out a true RF tight screen room you will find just how small an opening RF can make it into. Put a radio on the counter, close the door. Radio still plays. LATCH the door seating RF gasket all around dual cage, radio falls silent. Just unlatch the door and radio starts playing. A true RF room is a complete dual fine screen (or solid metal) cage with inner cage grounded to outer cage at only one point. All power and signals must be fed in through RF feedthrough caps.

However a much cheaper but also much smaller solution exists. 3-M static bags. Aluminum coated inside and outside, but layers not connected. Put whatever you wish to protect inside and roll edge, TAPE shut. DO NOT STAPLE. That just connects inner sheild to outer.

Its a matter of degree. How strong is the EMP to begin with? How far does it travel? What it encounters on the way? Anyting electricaly conducting will convert the electromatic energy into electricy. That is what does the damage to electronics. But if the EMP encounters ground (like a hill), the walls of a concteet building with steel renforcement, the body of a car, that energy will be deminished. As with so many things - it depends. I just wanted to put a qualification on the notion that EMP from the sun or an atomic blast might damage a lot of electronics, but certainly not all.
