According to an article in today's business section of the Toronto Star
newspaper, the vacuum tube turns 100 years old on Nov 16, 2004. The
article focuses mainly on the longevity of the vacuum tube in guitar
amps as well as mentioning their use in microwave ovens. Didn't mention
the tubes in my 3 footwarmers here.

Excellent one Hans....

This is truely THE MOST IMPORTANT invention of modern times...

Once we could amplify... all else was possible. Everything electronic at
least... How else could we have part of the internet running on Mars??? ;-)

Thanks...
