Just like our ears, musical instruments and just about everything else natural, tube amplifiers have the least distortion at the lowest levels. This is why a tube amplifier can sound great played softly, while with transistor amplifiers people are usually needing to turn it up to have it sound best.
Plus, do tubes sound better than transistors? Tubes, like analog recordings, have a more full-bodied sound than transistor gear. There's a "roundness" to tube sound that solid-state gear never equals. Tubes are less forgiving about mismatches, so to get the best out of a tube amp it must be used with just the right speaker.
In addition to that, how do you make a 12v amp circuit?
The electrons flow out of the tube via the anode (plate) to generate an electric current. In a small signal (preamp) tube, the anode current is fed to the control grid of the power tube. In a power tube, the anode current is fed to the output transformer input winding. Grid – also called the control grid.

Circuit works great for amplifying smart phones (adapter cable required).
Because valve/tube amps have an output transformer causes the amp to have a 'high output impedance'. ... This is a form of distortion, as the speaker is not following exactly the signal the amplifier is feeding to the speaker. This is the only reason a tube amp 'can' sound louder than a elderly transistor amp design.
Why Low-Wattage Tube Amps are Louder than Solid State AmpsTube amps are often perceived as being louder than solid state amps and this is because they actually are. A low wattage tube amp, of say 10 or 15 watts, will actually sound as loud or louder than a solid state amp of 50 watts or more.
