3-7 Watt audio amplifier (TDA 1519 A or 2N3055 transistors) with tone control By Ko Tilman
eBook (PDF): $1.66
This document (20 pages, PDF file) describes a stereo amplifier, made with the TDA 1519 A Chip or with 2N3055 transistors (conventional amplifier with an output capacitor). Also the schematics from... More > two tone control units (a presence/loudness filter and a parallel T filter) are published. With these filters you can create the type of sound that you like in your audio system. The document refers to a series of video's on my Youtube channel (called: "developing a 6 (4) Watt stereo amplifier"), the circuit in this video is published here. The tone control/parallel T filter only works with 1 switch, so there is no separate control potentiometer for "low" and "high" frequencies. The amplifiers need a good quality loudspeaker box (with some bass boost) to show their good properties. The document does not supply a schematic for a power supply with which the amplifier can be connected to the grid (110-230 V - 50/60 Hz). Copyrighted content.< Less
