Answer:
Transistors are better when it comes to dealing with heating issues. For a vacuum tube, you need a heater for it to work correctly. This heater can cause issues too.
The transistor takes the larger slice of cake in this one as well because of its better build quality. They are a solid-state device, which is much more durable than the glass build of vacuum tubes.
The transistors are different than each other in every batch. Like, one transistor might have β, which can differ from 100 to 600. Hence, manufacturing takes more time and work. However, vacuum tubes are much more convenient to build and work within this department because you always know what you are going to get.
Size matters a lot. Big things are always hard to manage and takes up a lot of vital space. We already know that vacuum tubes need heaters to run. So, they take more space.
It would be best if you had a high voltage gain when you are working with amplifier circuits. High voltage gain is pretty necessary, and transistors are perfect for this.
Step-by-step explanation:
transistors are much smaller than vacuum tubes and more efficient. They are very convenient when it comes to portability, but vacuum tubes make the circuit much more massive.
