06.49
The delay is intended to switch on the mains to heavy loads gradually to ensure that the switch-on current remains within certain limits and to prevent the fuses from blowing. The elements that cause high currents at switch-on are, for instance, the electrolytic capacitors in the power supply of an output amplifier. Since these are not charged at switch-on, they constitute a virtual short-circuit on the supply lines. The current can, however, be kept within limits by inserting the present delay circuit between the mains outlet and the transformer...

This project is inspired by the article of the ELEKTOR magazine of july/august 1991. It is based on the basic principle of a loudspeaker delayed turn-on and DC entry detection (+ 1,5 V and - 0,7 V). This module lies between the amplifier output and the loudspeaker output. When the amplifier is powered on, a temporization of engagement of +/- 2,5 seconds delays the starting of the loudspeaker (avoiding power on thumps). If a continuous tension appears on the amplifier output this module immediately interrupts the loudspeaker line.Leds indicate the...

This amplifier operates a control non-symmetric so that the benefits to be rather simple symmetrical version. Other merit, because there is only one round (loop) negative feedback so that high frequency stability to be easy. The presence of C7 between two points such berimpedansi high enough peredaman guarantee against a very good high-frequency oscillation. This must be done on the struggling symmetrical design. Few people realize that excess heat is dangerous to the transistor if the power is generated by the oscillation frequency is not high...
