This paper discusses a new kind of distortion mechanism found in transistorized audio power amplifiers. It is shown that this distortion arises from the multistage feedback loop found in most high-quality amplifiers, provided that the open-loop transient response of the power amplifier is slower than the transient response of the preamplifier. The results of the analysis are verified by measurements from a simulated power amplifier, and a number of constructional rules for eliminating this… 
A PowerAmplifier "Improver"*
An add-on facility for audio power amplifiers is described, by which nonlinear distortion products in the audible range of frequencies are reduced by a typical 25-30 dB. The improver uses the
An Audio Power Amplifier for Ultimate Quality Requirements
A 50 W/4 Ω complementary symmetry audio amplifier concept is described. The amplifier is designed to meet ultimate quality requirements with particular emphasis on lack of transient intermodulation
Power amplifier design criteria
The initial requirement for audio power amplifier design to drive the typical high fidelity loudspeaker of 8 Ω nominal impedance would appear to be easily satisfied. However closer inspection of the
Small-Signal Distortion in Feedback Ampliers for Audio 1
TLDR
Though negative feedback usually improves the distortion characteristics of an amplifier, it is found that in some cases it makes the distortion “messier” and casts light on the relative virtues of the three types of active devices and the three circuit types.
Prediction of the transient intermodulation performance of operational amplifiers
Abstract Closed-form expressions are obtained for the THD, THD-20 and MIM tests used to characterize the TIM performance of operational amplifiers and circuits of similar topology. Good agreement is
The theory of transient intermodulation distortion
The existing theory of transient intermodulation distortion (TIM) is extended to cover the calculation of the duration of intermodulation bursts. It is shown that feedback values in excess of some 40
A model for slew-induced distortion in single-amplifier active filters
Under certain conditions of operation, the operational amplifier has the rate of change of its output limited to a value called the slew rate. This effect can result in slew-induced distortion (SID).
Transient intermodulation distortion--Part I: Hard nonlinearity
Otala's suggested rules for eliminating transient intermodulation distortion (TIMD) in a low-pass feedback amplifier have been widely and wrongly interpreted as being necessary. In fact, the

Modelling of Non–Linear Distortion in Vacuum Triodes Using Trans–Characteristics Inverse and Newton’s Method
The increased interest in vacuum tube audio amplifiers led to an increased interest in mathematical modelling of such kind of amplifiers. The main purpose of this paper is to develop a novel global
