This varied widely with the type of tube. Many common radio tubes cost less than 25 cents. A picture tube for a TV might be $50 to $100 depending on size. High power transmitting tubes could cost thousands of dollars.
The following stores sell a vacuum tube. Walmart, Home Hardware, Rona, Totems, and much more. Some of the stores listed might not sell a vacuum tube depending where they are located. These stores are located in Canada.
A vacuum tube is simply a tube with no oxygen nor carbon dioxide in it (aka no air).
There were obvious differences between the trasisitor and the vacum tube. The transistor was faster, more reliable, smaller, and much cheaper to build than a vacuum tube. One transmisor was the equivalent 40 vacuum tubes. They also didn't produce heat compare it to a vacuum tubes. Conduct electricity faster and better than vacuum tubes.
Kilobytes and vacuum tubes are not in the same category. At best, a twin triode vacuum tube is a single flip-flop and can hold 1 bit of information, making a vacuum tube about 0.000122 of a kilobyte.
an electron tube containing a near-vacuum that allows the free passage of electric current.
It will cost you about $743.00 to replace a vacuum tube on a Ford Focus 2002.
The transistor replaced the vacuum tube, allowing radios to get much smaller and portable.

The following stores sell a vacuum tube. Walmart, Home Hardware, Rona, Totems, and much more. Some of the stores listed might not sell a vacuum tube depending where they are located. These stores are located in Canada.
A vacuum tube does not contain any gases. All the gases are evacuated from the tube and only vacuum is left.
A vacuum tube is simply a tube with no oxygen nor carbon dioxide in it (aka no air).

A tube of toothpaste cost about $25.98 in 1935
who made the vacuum tubes
A replacement tube (if it is available) is likely going to cost almost as much as the whole television. If you need a new tube, it's time to ditch the tube TV and get a flat screen.
