Not expensive, High-quality sound, Small parts and easy to assemble, Do not need to be tuned.Today can offer to your attention an amplifier that I have gathered from (almost) stuff I have lying in store. Long ago, working in the workshop, we often filmed amplifiers machines, since they come without tape recorders and to put an ordinary tape recorder had to dismantle the amplifiers are !!! I left a couple of times since amplifier chips such as the LA4708. Time has passed since then a lot until my sister had not asked to do anything for his laptop to play in the yard with an acceptable quality and loud sound as speakers 2 pcs idle at home!
It is taken from the datasheet half and half just from the people and schemes are proven over the years !!! If you look at the diagram, the capacitors C3 and C4 - a savings standing on the output of the amplifier, without a way (as if the sound disappears at high bass and not enough to drive the speakers). The amplifier where I desoldering the chip standing at the entrance storage choke (but I was too lazy to shake it, because it was a little too big standard, and the image at the top of his nebylo), it was decided to do without it !!! Increased denomination was in microfarads and capacitor C7 to 3300 microfarads, put dop.kondensatory input to the sound source and of the zener instead I put krenochku 5V to 5 foot (because it was under the hand) Well, all of the components that we need:
Sorry I forgot to add a couple of SMD capacitors there, standing at the entrance, but roughly the size of clear =) I must say that the capacitors C1, C2, C5, C6 (Mylar or polypropylene). Next Ludim, drills, soldered components from small to large. Unfortunately I lost zaglyuchila feshka and photos with my tinning and soldering = (There was only the result of the test and for 2 weeks =)
Put it on the active cooling, in Signet will be provided !!! My advice is not to actively, but rather to increase the area of the radiator. The following seals:
Power gives its net 20-30 watt channel! Tested on AS35! Keep in mind that this , no volume controls are not present !!! Before starting up the volume to a minimum !!! Starts amplifier from normal BP computer, it still works as well (there is no time to stick his body =)
