Vacuum tubes have been built in sizes as small as the eraser on the end of your pencil to as big as a bus. It all depends on the purpose and power requirements. The typical vacuum tube used in household radios and TVs was half an inch to one inch in diameter and two to five inches tall.
It used 5200 vacuum tubes.

Without the transistor you would need vacuum tubes to accomplish the same thing. None of our inexpensive portable electronics would be possible using vacuum tubes.
It was difficult to change directions and the vacuum tubes always burned out

Vacuum tubes initially led to an increase in size of electronic devices due to their bulky nature and need for additional components. However, as technology advanced, the development of smaller, more efficient components such as transistors and integrated circuits led to a decrease in size of electronic devices.
It used 5200 vacuum tubes.
Solid state components, such as transistors, are more reliable and efficient than vacuum tubes. They are smaller in size, produce less heat, and consume less power. Additionally, solid state components do not require warm-up time like vacuum tubes do.
I'm not sure what you mean by "this computer" but vacuum tubes have the following problems anywhere they are used:high voltage required for operationget very hotshort lifetime, heater burns outlarge physical size
No, there are some cold cathode vacuum tubes. These do not light.
who made the vacuum tubes
This would depend on the type of vacuum tubes needed. Any car part store will carry vacuum tubes for a car, general stores carry vacuum tubes for household vacuums, and AC part stores will carry vacuum tubes for the AC/Heating system of a house.?æ
Bell Labs researchers were unsatisfied with the low reliably, high power usage, and large size of the vacuum tubes that needed to be used in the telephone switching and long distance trunk systems of the 1940s.
ENIAC was the first digital general purpose computer, built in 1946, and with 17,468 vacuum tubes. The Illiac I, the first computer built and owned by a US educational institution, had 2800 vacuum tubes. The IBM 604 had about 2000 vacuum tubes.
Vacuum tubes were first replaced by transistors, and later by integrated circuits.
Modern devices use integrated circuits instead of vacuum tubes because integrated circuits occupy less space than vacuum tubes, are more efficient, consumes less energy and are more reliable than vacuum tubes.
