e bem ga - nesto me nece This paper proposes a variant of the transistor stereo amplifier based on the popular in his time among the music lovers a tube amp "Surf-204" or "Surf-104. In fact, from him shall be used only housing, power and output transformers. Using the compensation method of linearization characteristics of amplifier stages and the use of devices with "built" feedback yielded little harmonic distortion from the low-order harmonics and low output impedance without introducing external negative feedback.The human ear - a non-linear transducer, as shown in [1], level of harmonic distortion in it decreases in energy terms, something like 10, where n - number of harmonics. In logarithmic terms, it is 10 dB at each interval between the harmonics. The initial data taken in tones G. Olson, D. Cheever were treated in [2] and normalized relative to the level of the test signal as shown in Fig. 1. It is seen that when the SPL of 50 dB (quiet voice) to 90 dB ( the level of sound in the studio) harmonic distortion produced by the ear when converting audible sound in the ear and its processing in the brain vary from 1.5 to 20% by the second harmonic and from 0,3 to 3% in the third. It turns out that if the amplifier will to signal a lower level of harmonic distortion, these distortions will be masked by the distortions of their own ear. Given that the hearing partially adapted to its own distortions, we establish the reserve in terms of spectral components of the distortion at 10 dB. This stock will not unmask distortion at low frequencies where the harmonics fall in the area of maximum sensitivity of hearing, and to ensure an acceptable level of intermodulation distortion to which the ear is more sensitive. As the author put the task of building a push-pull amplifier (in such amplifiers in the spectrum of the fundamental harmonic distortions of the third), the guide will serve as a value of 1% third harmonic distortion at an SPL of 90 dB. Also from the graph that at sound pressure levels up to 70. .. 80 dB amplifier should produce higher harmonics, starting with the seventh.In [2, 3] showed that by closing the feedback loop is expanding the range of harmonics. Amplifiers with vacuum tube triodes and field-effect transistors have a transfer function close to a linear-parabolic. Amplification on a powerful field-effect transistor at the level of distortion for the second harmonic of 10% before closing circuit CCA creates sharply falling spectrum. After the closing circuit HSE produces a wide spectrum of the reduced level of distortion.In the same papers [2, 3] shows the calculated characteristics of the relative amplitudes of harmonics as a function of the depth of CCA, and for the calculations was chosen quadratic characteristic of the cascade, not covered by the feedback. Dependence of the level of harmonic distortion of this stage of the depth of the feedback comprising a cascade is shown in Fig. 2. Since the transmission characteristics of real amplifying elements include not only the quadratic term in the expansion, D. Cheever spent the corresponding measurements on a powerful field-effect transistor with insulated gate. At a depth of CCA to 5 dB levels of harmonics from the third to sixth little changed, with greater depth as the real values of CCA were close to settlement, but always more. As a result, it is clear that there is a significant increase in the level of higher harmonics at a depth of DUS is often used in practice. Application of deep-CAB (50 ... 60 dB) is difficult to ensure the stability of the amplifier to the same depth in such amplifiers CCA usually subsides already on sound frequencies. There are other negative properties of deep-EP (about them below).Real power does not consist of one stage, and transistors, which results in the production of a wide spectrum of harmonics above the threshold of visibility, which in turn improves the intermodulation distortionSolutions for the creation of amplifiers that meet the requirements of psychoacoustics.1.Creation amplifier with deep CAB to use it to try to suppress the higher harmonics [4, 5].2.Postroenie amplifier without overall environmental protection. For linearization in this case, use a few local chains CCA [6].3.Using amplifier stages without introducing additional environmental protection. (Hi-End).The choice of transistors for the output stage is very important.In tube amplifiers without the CCA in the output stage using triode, which has a small output resistance, which is using the output transformer is reduced to an acceptable level (2 ... 3 ohm load at 8 ohms). Search for transistors having similar characteristics have led to a class of field-effect transistors with a static induction channel. Transistors of this type abroad are products of the firm Tokin (Japan). There are also examples of amplifiers with their use [7]. Purchase these transistors in Russia now is not possible. Were developed by native transistors with a similar structure: a series of KP801, KP802, and KP926. The first two are no longer produce or sell, and the latter is more common in the market. The current-voltage characteristics (CVC) of the transistor shown its proximity to tube triode.The maximum power that can be removed from such a cascade in the linear regime (subject to restrictions on the minimum voltage and current), isPout = Uout Ivyhm m * / 2 = 120 * 0.13 A / 2 = 7.8 Wthat corresponds to the voltage at the load 11.2 in 8 ohms. Thus, to reconcile with this load will require a transformer with ratio 11.2 / 120 = 0.0933. Converted to the secondary winding output impedance of the cascade without losses in the transformer turnsR'vyh = Rvyhn2 = 540 * 0.09332 = 4.7 ohms.It's a bit much, so was selected push-pull configuration, which reduced the output impedance, increase output and improve the linearity of the amplifier.Scheme and the amplifierWiring Diagram nodes stereo amplifier is shown in Fig. 3. Each channel amplifier has two inputs: a simple (X2, X4) and balanced (X1, HZ). When a signal from the symmetric source should be open contacts switch SA1. In the amplifier volume control is built according to the scheme L-controller [8]. This allows you to reduce insertion adjusting resistor noise and distortion.
