Transistors used less power, high speed types of transistors began to operate faster than tubes, lower voltages needed, less power dissipation, and greater reliability.
Note the early junction transistors were too slow for anything but audio amplifiers. It took about a decade to solve this problem. The first radios to use transistors were called "hybrid radios" as the RF and IF sections still used tubes.

∙ 10y agoFor electronics such as processors: size (a transistor is millions of times smaller), cost (a tube-based circuit is more costly than a semiconductor equivalent)
For audio: The tube requires to reach its operating temperature before operating optimally, the transistor equivalent is instant. Most audio today comes from a digital media (CD, MP3 etc.) where the semiconductor digital to analog converter can be implemented much better. The tube has some advantages in the amount of current it can draw, but that is outweighed by cost drawbacks.

What technology replaced vacuum tubes in the second generation?
Vacuum tubes were first replaced by transistors, and later by integrated circuits.
Transistors replaced to amplify electric signals?
vacuum tubes
What are silicon chips replaced of?
Silicon chips replaced individual transistors and before that vacuum tubes (valves).
What replaced vacuum tubes in the computer?
Integrated circuits (in many microprocessor integrated circuits) containing many billions of transistors each.
What roles has vacuum tubes played in computer development?
vacuum tubes are the switching components in the first generation computers to process data. later they were replaced by transistors.
Which invention replaced vacuum tubes in computers?
Transistors were first developed in 1947 by Bell Telephone laboratories. They replaced vacuum tubes, which were big, bulky, costly, and unreliable. Transistors are most often used to regulate the flow of an electrical current and to switch electricity on and off.
What is transistorized?
A device such as a radio can be said to be transistorized when earlier designs are replaced by designs in which transistors replace vacuum tubes.
How did colossus work without transistors?
There were vacuum tubes before transistors
Vacuum tubes are still found in most electronic equipment?
no, they have mostly been replaced by integrated circuits and a few discrete transistors.
What do you call the vacuum tubes used in transistor radios?
You don't, there aren't any. However some radios in the early 1950s did use both vacuum tubes and transistors. This was because early junction transistors were too slow to operate at RF so vacuum tubes were used in the RF and IF sections. These radios were called hybrid radios because they used both vacuum tubes and transistors.
Why were the vacuum tubes used instead of transistors in early computers?
Early transistors were much slower and far more expensive than vacuum tubes. Also computers built before 1948 there were no transistors to use at all.
How did major development in the second generation computer change the computer?
Mostly the machines got smaller and more reliable as transistors replaced vacuum tubes.
