Well not really. I was given a duff 211 transmitting valve and hatched a plan. Raiding the junk box and the LED draws I came up with this unusual table lamp.   |

The same, but opposite! I made two of these; squirrel cage bulbs, bike brake disc spacers, aly rod and wooden bowls from a charity shop. I run them in series, as the filaments vibrated at 240 volts, and they were too bright anyway. I took them to Scalford one year, and sat in front of a friend's system they got more interest than his gear, as people kept asking what amps they were!  082 by Richard Crawley, on Flickr |

Apart from the bulbs, which were discounted at Next, and two cheap switches, I already had everything else. The spacers I made years earlier for a motorbike I was building, but didn't complete, commercially it would be expensive to produce. I have some more of those bulbs, and some fridge bulbs, and a plan! Combine them all in one chassis, with a couple of meters (which I have) and it will look like 300Bs and 6SN7s.

Looks very steampunk, which is somethingbim liking at the moment |

Definitely a business idea here as I am sure lots of Audiophile would love to have something like this. Would make an interesting decorative feature in your man cave and bring about a bit of Higgy!

Returning to Alan's original lamp, how bright is a 211 in normal use? I used to have 845s, and they used to light up the room! Would running them with just the heaters connected do the same?

Could an old valve be mounted into a valve base, then attached to a wall wart to make a stand alone lamp?
I know it's a bit excessive bit its pretty simple in the idea

845's need 32W on the heater so it would be a chunky wall wart  |
