Puzzled About Amplifiers ? - Norman
H. Crowhurst Is a triode amplifier better than a pentode amplifier, or vice versa? The author shows that either type of tube can incorporated into an excellent amplifier if the design is correct -- and then he tells about some of the design problems. |

High-power Audio Amplifiers - Mannie Horowitz As we increase the power output of an amplifier, we run into a whole new set of problems which are of importance to the designer and which must be solved properly and efficiently. Learn what these problems are and how they have been handled by one manufacturer. |

Push-pull in Hi Fi - Mannie Horowitz The push-pull amplifier has become standardized as the optimum circuit arrangement for providing adequate power output with a minimum of distortion -- so long as tubes are used under proper conditions. The author makes the performance of this type of amplifier thoroughly understandable. |

Simplified Push-pull Theory - Julias Postal Part 1: A graphical, non-mathematical explanation of how second-harmonic and other even-order distortion is reduced or canceled in push-pull stages, and a discussion of why push-pull operation has no effect on third- or other odd-order distortion products. Part 2: Continuing the discussion of push-pull operation and why second-harmonic distortion reduced or canceled completely whereas third-harmonic distortion is not affected. |

Push-pull A.F. Amplifiers - K. R. Sturley Ph. D. Problems of the position of the composite load line and the construction of the valve load curves for classes A, B and C audio-frequency push-pull amplifiers are discussed and it is shown that B. J. Thompson's original work on class B amplifiers with matched valves can be extended to cover all classes of push-pull amplification under matched or unmatched conditions. Deductions regarding composite and valve-load curves as a result of voltage and current measurements are confirmed by photographs of valve-load curves obtained on the screen of a cathode-ray tube. |

System Design Factors for Audio power Amplifiers - M. V. Kiebert, Jr. - P. R. Mallory
and Company Prior to going into purely technical details, it appears to be desirable that an evaluation be made and some conclusions drawn as to why there should be . . . such disparity amoung the findings of the various A-B listening tests [ . . . ] |
