I got a snip from wiki about valve (tube) amplifier that made me curious:

The Soviets retained valves to a much greater extent than the west during the cold war, for the majority of their communications and military amplification requirements, in part due to tubes' ability to withstand instantaneous overloads (notably due to a nuclear detonation) that would destroy a transistor.

SO...what would protect my rig from a nuclear blast? A giant lead fridge? ...seemed to work for Indiana Jones.

..yes, this is paranoia, mythbuster-addict that I am I like to throw money at oddities and potential problems

What is the point of this thread? Did you read the welcome PM... maybe this "question" is better served at Headfi.

This is offtopic section so I thought it'd be fine. Sorry, requesting thread delete.

With the rare exception, there are no thread or post deletes here, and your edit window is only a few minutes. It's a good idea to think before you post.

Yeah EMP's (electro magnetic pulses) are a problme for headphone listening. "Oh no, I can't listen to my headphones with these damn nuclear bombs going off all the time... "

So that's why I have syphilis, I thought it was my ill-functioning power conditioner all this time.
