The introduction of this work provides some information about audio and human hearing on audio signals, audio tube amplifiers and cartridges types used in turntables. During the work is presented a step by step design of a RIAA stereo phono tube preamplifier, how to choose the operating design point of an electronic valve and the power supply design to the amplifier circuit. It provides information on passive filters and the RIAA equalization circuit responsible for carrying it out. It also provides all simulations performed in the projects, both the preamplifier circuit as the power supply. In addition shows the results obtained experimentally for the source and specialy this research also provides the functional testing of the preamp, specifying circuit gain, accuracy of the RIAA curve, input impedance and output impedance, signal-to-noise ratio, total harmonic distortion and the conclusions obtained after the work. |
