A volume setting passive integrated possible by the high output level of modern sources, and a structure of the amplifier gain sufficient floors limited to essential guarantee the transparency of the system. Yield loudspeakers and damping for ‘pregnant will be the selection criteria.
A Release to push-pull “common drain”: his first schemes have 20dB of reaction against the level of DHT + noise is less than 0.05%, bandwidth than 200kHz. Le gain est de 29dB (x28). The gain is 29dB (x28). Very goods for pregnant crossover agreement and bass reflex. The damping more than 100 are pure generating tension.

3A 5V Switching Regulator
In principle we should compare it with the previous design is possible to obtain an adequate tension on the exit of the first transistor and to activate la puerta del mosfet. Modifying a pair of resistance can not obtain the appropriate tension to activate a one-channel mosfet P, placed in substitution of BD136. As resistance in ON is very low improves the operation in general, and allows me to currents of salida much higher that a bipolar transistor.
