Valves are NOT dead .....

The mind boggles when you think about what time, effort and accuracy of design and build is required to make these things work.

Very pretty !! Heh, would be great in a cold climate to offset the heating bill :-). Some project !!

How does using electricity to heat a valve filament offset your heating bill? (especially if you don't normally use electricity for heating) It certainly increases your cooling bill though.

True story: When i was a teenager, we had a water fight one day. I had a twenty dollar note (paper) in my pocket. I thought the quickest way to dry it was to place it on top of my old valve radio. An hour, or so, later I returned to find a small pile of ash. Twenty dollars in those days was half a weeks wages.

AHHHH rrriiiiggghhhtt !! Glad ya enjoyed the joke Enstein :-)

I chuckled, anyway. ;-) If you reckon that clock's complex using valves as logic elements, think about the Colossus computer with 1,500 valves used by the Poms in WW2 to help break the German Enigma codes

That would have been great in the middle of winter! Bob

have a old muse tube amp, used it on a amstrad computer, in the winter i used it as a foot warmer.

Yup, the Poms arent all that silly either !! Good little number in winter as ya say :-)

I like the Nixie Tube Cable TV set top box here

Exellent effort, if not bizarre.

And in summer?

MrT.

It's still a foot warmer but hotter.

in summer i could keep my coffie warm.

I've got a valve that is dead.

geoff

i got a new valve long time ago its a 6L6WXT it was dead, no cathode connection to pin from inside.

They used to strip off to keep cool in the computer room - quite a few of the female operators got knocked up while working there!!!

A documentary on UKTV history channel about Bletchly Park - the codebreakers. One of the original codebreakers in an interview mentioned that maternity leave was higher among female staff at BP and attributed it to the removal of garments in the heat of the computer room!
