The successful metal pressure tube anemometer of William Henry Dines in 1892 utilized the same pressure difference between the open mouth of a straight tube facing the wind and a ring of small holes in a vertical tube which is closed at the upper end.

The tube length determines whether the tube acoustic pressure or velocity is the dominant influence on the frequency of the tube.

The Williams tube would prove more capacious than the Selectron tube (the Selectron was limited to 256 bits, while the Williams tube could store thousands) and less expensive.

While this pollen tube is growing, a haploid generative cell travels down the tube behind the tube nucleus.

Dual-mono and stereo, mid/side microphone support, and a replaceable vacuum tube, further expand the personalization offered by this tube preamp, making it an ideal option for music lovers of all levels.
