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. 4 531 KB 530 KB MUCH Smaller Files Coming                   0002 Amplifiers - Edgar M. Villchur An analysis of the fundamental nature of amplification, and a description of the working principles of pneumatic, mechanical, carbon, vacuum-triode, magnetic and dielectric amplifiers 6 993 KB 994 KB Ditto                   0005 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. 4 344 KB 340 KB Ditto                   0010 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. 4 366 KB 363 KB .Etc.                   0015 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. 8 696 KB 695 KB                   0020 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. 6 909 Kb 909 KB                   0025                             0031 Circuit Features in Hi-Fi Power Amplifiers - R.
