I have old tube equipment and I usually leave it on for a long time. I was told that his consumption is high and that he uses a lot of energy. It is true?"
A tube device uses most of the energy to heat the tubes and its performance is low. We can say that, for a 5 W tube amplifier and the 5 W transistor amplifier, while the transistor uses 10 W of energy, the tube can spend 30 to 40 W. As these values are low considering the usage time of each one, consumption should only be analyzed if they are used in a system where this factor is very important, for example, in ambient sound, or even when they are permanently on.
