Here is a simple audio amplifier using a TL431 shunt regulator. The amplifier will provide room-filling volume from an ordinary crystal radio outfitted with a long-wire antenna and good ground. The circuitry is similar in complexity to a simple one-transistor radio but the performance is superior (with the exception of the […]
In the below exist a classic preamplifier PHONO of correction RIAA, for those who they insist they use disks of vinyl. For good precision in the reproduction of sound, should the materials that find in the negative feedback and correct RIAA, to be good quality, as resistors of 1% metal film, the […]

For the modules of inputs stereo, exist two choices, that appear in the circuit below. The first choice in left, it is in symmetric input connection [ balance ], while in the right, exist one of simple asymmetrical input connection [ unbalance ].
The gain of also two units is one. This gain can increase itself, […]
