2005年4月2日 · Conclusion. Class-A is the most desirable of the amplifier configurations from a purist point of view, but is not suited to high power systems unless outrageous power dissipation is acceptable (like between 825 to 1500 Watts of pure heat, to get 300 Watts of audio).
- 1.58 Amps RMS (2.23 Amps Peak)
- 20W (continuous)
- 12.65 Volts RMS (17.9 Volts Peak)
- +/- 20 Volts (constant)
2021年1月22日 · Players and amp-makers often talk of sweeter distortion in class A amps, but true class A operation actually has less distortion content at any given output level; although it displays a smoother onset of distortion when it comes, and one that is usually heard as

2023年8月2日 · The quality of this filter has a great bearing on the overall sonic performance. The major plus point of Class D is that it is very energy efficient. A typical Class A design tends to be around 30% efficient. Class A/B roughly doubles that while Class D amplifiers almost triple it.
2019年12月21日 · Certainly, we could say that many Class A topologies generally are sweeter and without the character-changes-with-level some AB circuits have—and we would not be too far off the mark—but consider that many of us have never actually heard a pure Class A power amplifier. In fact, what we think of as Class A is generally found in a small ...

On its surface, the term "Class A" implies "best," "top-of-the-line," and so on, like "Grade-A beef" or "first-class ticket." After all, you wouldn't buy Grade-B beef for your family, right? So who wants Class B tone? But that's not at all how this class thing works. And just to be clear, while you really don't want Class B tone (which exhibits hig...
As for great Class AB guitar amplifiers, how about Fender's tweed Bassman, Pro, Super, and Twin, and the blackface Bassman for that matter, as well as the Deluxe Reverb, Twin Reverb, Super Reverb and everything in between? Or Marshall's JTM45, Plexi, and JCM800 models, or Hiwatt's legendary stacks, or the original two iterations of the Mesa/Boogie ...
Rather than immediately assuming a guitar amp strictly fits the textbook definition of Class A every time you see a manufacturer use the term as part of their promotional material, look at it like this instead: It's very hard to know whether any supposed Class A amp is actually functioning according to the strict definition of Class A without getti...
That's a reasonable question. Or, put another way, "how does my understanding of what's going on inside any supposed Class A amp help me to be a better-sounding guitarist?" In and of itself, it doesn't. But it just might serve several useful purposes in your tone quest by: 1. Letting you know that an amp billed as Class A isn't necessarily better t...
Such operation results in the smoothest transfer function and the widest bandwidth. The System A amplifier has a clarity and a tonal response that produces a superior perspective of depth with a sense of reality: instruments appear in precise position out of a silent background.
2005年1月12日 · Advantages: – The tube is ready to amplify the signal at all times. – The signal is instantaneously amplified because the tube does not have to “wake up: from a less than full operational state. – A 30 watt Class “A” amp will sound louder than a 30 watt Class “AB” amp. – Because current is maximum at all times, the amp will ...
