The three standard forms of analog amplifier biasing are:class A - the amplifier is biased in the center of its linear operating range, this is the most linear but least efficient type of amplifier (because the transistors or tubes are always conducting, even when there is no signal to ampliify).class B - the amplifier is biased at the cutoff point, this is an efficient amplifier but is only linear if operated as a push-pull amplifier (because the transistors or tubes are in cutoff and not conducting when there is no signal and through one half of every cycle, a class B push-pull amplifier has two sections that operate on alternate halves of the cycle).class C - the amplifier is biased in hard cutoff so that only the peaks of the input signal are amplified, this is the most efficient amplifier (because the transistors or tubes may be in cutoff and not conducting for more the 85% of the time) but it is not capable of linear amplification. An amplifier biased as class C is only suitable for use in RF transmitter power stages, where a resonant LC tank circuit will be excited into oscillation by the output of the amplifier and complete the missing parts of the cycle.There are other forms of biasing (e.g. class AB) analog amplifiers that get some of the advantages of two of the standard forms. There are also forms of amplifiers having other nonstandard classes (e.g. class D) that are not analog amplifiers, but instead operate by amplifying pulses.
Rectification mode makes the power conversion process more efficient.
A: TUBE AMPLIFIERS are operating at higher voltage which makes the dynamics of amplitudes more desirable. Other then that there is no other reason. tube amplifiers are bulky heat generating components efficiency poor and frequency limited.
They certainly are. Using them together with carburetted engines can be a bit tricky, and usually the compression has to be lowered when compared to a naturally aspirated engine.
Output of the power amplifier is smaller 0.1 ohms and input of the loudspeaker is more than 4 ohms.
Depends on the class ratings class a/b are less efficient class ds are more efficient but usually monoblocks amps even if it is "2 channel" are wired to just one set of positive and negative input on the inside of the amp hence the term monoblock
Class C amplifier.. A class D amplifier is more efficient than class B, and is more efficient than class C as well.
Someone can sell their Class D amplifiers by putting a listing up on eBay or Amazon. Amazon is the best choice because your item will be more likely to sell.
Car amplifiers can be as loud as those which have more than 1000 watt power. The Loudest TL-1021 series from WIKIO are some of the loud car amplifiers. Audio Assault also comes out with car amplifiers of 1000 W.

No. Mosfets are used for their switching capabilities more then amplification purposes if anything. for Pulse width modulation, power supplies, for certain frequencys, and smoothing out power sources, signals, and PWM can be used in class D amplifiers as well to have a very good efficiency.
Steam power is more efficient.
The short exhaust should be more efficient and increase power.
yes
Amplifiers and better speakers. But amplifiers are a must.

A: There is a misconception of understanding of terms here. A power amplifier is called that because it has capabilities to derive power from it .It does not create power it actually uses more input power then the power delivered, In other words it has a decrement in efficiency
