Thinking about building yourself one of these cool Vacuum Tube Lamps? I think these are more artistic than anything. Who cares how it works, it “looks” great. I WANT ONE!
The basic circuits are rather similar, but the new project has a number of differences. Most notably it is easier and less costly to build. The rather large output transformers used in the original project have been replaced by ones that are considerably less weighty and less costly. This alone makes for a $40 to $50 savings.
