Why is a transformer needed?
... What do the terms "peak inrush current" and "exciting current" mean and how do they relate to transformers? Exciting current is the amount of amperage a transformer draws under a no load condition. Another way to look at it is that exciting current is the transformer's "idling" current. Exciting cur ...

Tube sound
![](https://commons.wikimedia.org/wiki/Special:FilePath/Tubes.jpg?width=300)
Tube sound (or valve sound) is the characteristic sound associated with a vacuum tube-based audio amplifier. After introduction of solid state amplifiers, tube sound appeared as the logical complement of transistor sound, which had some negative connotations due to crossover distortion of early transistor amplifiers. The audible significance of tube amplification on audio signals is a subject of continuing debate among audio enthusiasts.Many electric guitar, electric bass, and keyboard players in several genres also prefer the sound of tube instrument amplifiers or preamplifiers.
