Regarding the power supply voltage to the +-75V. VC comparing the performance of the modified Leach 700W/2R on one common board of both channels, as well as protection and control circuits for the fans. Regardless of what tubes I used for outputs, the sound is «silky» and refined. The increased gain is only used when a very low input signal is to be amplified. In a previous article I discussed building audio amplifiers using discrete transistors. Circuit author publicates in a February 1976 in american journal.


The basic operation of a switch-mode power supply is fairly straightforward, and ATX supplies have very few deviations from the norm. Maybe it was the tube computer sound card idea I have seen, or the fact that I have enough junk to fill a dump truck. One reason for that, but hard to find and the LM3886 integrated into the original cost of a fact to be taken into consideration. In this project, in which hosts two LM3886 LM4780 integrated with Integration, ie, making a complete amplifier.

There are a variety of integrated circuits you’ll find running the show whose data sheets will often give you an entire ATX power supply schematic, but since their circuitries will often be very similar we’re showing you one of the most common. The problem was that some of the golden ears of the large power supply rejection IC spec saw and thought it meant that the chip could tolerate the 10V power supply ripple. But it does not produce high quality audio… For many applications, the advantages weigh more than the distortion and noise of this chip, so that I used it anyway. In other cases I used different chips, which perform better but need more complex circuits. Now you can kick back on the sofa and surf all your favorite channels in superior fidelity. Power output can range from about 325 mW to about 750 mW within this supply range when using an 8 ohm speaker.
