High-End Power Amplifier LME49810 2SC5200 2SA1943

High Power Amplifier LME49810 2SC5200 2SA1943

High-End Power Amplifier Circuit using ic LME49810 as a driver amplifier and using Transistor 2SC5200 2SA1943. LME49810 is a high fidelity audio power amplifier buffer driver. 

High-End Power Amplifier output power may be scaled by changing the power supply voltage and number of final stage transistors (Transistor Booster) . The LME49810 minimum output current is 50mA. When using a discrete output stage the LME49810 is capable of delivering in excess of 300 watts into a single-ended 8Ω load. 

Unique to the LME49810 is an internal Baker Clamp. This clamp insures that the amplifier output does not saturate when over driven. The resultant “soft clipping” of high level audio signals suppresses undesirable audio artifacts generated when conventional solid state amplifiers are driven hard into clipping. The LME49810 includes thermal shutdown circuitry that activates when the die temperature exceeds 150°C. The LME49810's has mute function, when activated, mutes the input drive signal and forces the amplifier output to a quiescent state.

2N3055 MJ2955 Booster Transistor Circuit

Before , this circuit is boost on Final transistor Power Amplifier 2N3055 MJ2955 , this modif in Final Stage amplifier by adding more 2N3055 and MJ2955 about adding 8 set transistor. Ouput gained to about 500Watt power output. All final transistor circuits are combined in parallel, see circuit diagram below 
2N3055 and MJ2955 about adding 8 set transistor

The addition of transistors you can see in the above schemes combine p2 - p6 correctly with Driver power amplifier. Do not wrong connect, because it can lead to broken transistor. We also completing with pcb board layout making it easy to assemble. Do not Forget to give cooling to the transistor. Place the transitor cooler attached between the pcb and transistors.

Simple and Manual LED Acrylic Sign Project

LED Acrylic Sign

A bit out of the discussion of electronics, but still on the basis of electronics that how to apply the LED circuit  in acrylic field. This is a Simple project on making LED acrylic sign. So I will share tips how to make it step by step. What is required and how to make use in LED acrylic sign.

First, this part and tools you need to making LED Acrylic Sign:
part and tool LED Acrylic Sign

Parts : 
  • Acrylic on image using Acrylic 10cm x 20cm 
  • Some Cable to connect LED with Power Supply or Battery
  • LED Strip's or you can assembled LED circuit, i will describe below.
Tools :
  • Pencil to draw sign on Acrylic Field
  • Sandpaper to sandpapering acrylic sign
  • Ruller to scratch that sign exactly at the right position
  • Cutting Plier to cut the cabel
  • Cutter to cut the wrapping layer of acrylic on the sign
  • Solder and Solder tin to soldering cable with LED Strip's or Assembled LED Circuit

If the parts and tools are ready , let's create a this LED Acrylic Sign simple project and so manual !
Take acrylic and drawing sign in reverse, in the picture below I write in reverse. This function to mark the acrylic wrapper to be exfoliated. in the next step.
Acrylic Sign

After you mark, peel the parts that are not exposed to a pencil.

DIY LED Acrylic

And if the acrylic is reversed, that text "" is clearly visible
Make Acrylic Sign

Then rub using sandpaper, on the part of the sign. This function to refract light LED, so that the LED illumination only on the sign.
Creating LED illumination

After all has been rubbed, then turn acrylic and open the wrapping on the front.

LED Beautyful

Paste the LED Circuit by using glue or other adhesive.
So Cheap LED

And if the LED is already neat, supply using a 12 Volt DC voltage.

Car power amplifier circuit using C5100 / A1908

Car amplifier is not very common as a project, because it is usually difficult to build, and expensive. A small error during assembly will result in power amps are not functioning properly. I suggest that you use the PCB for this amplifier. Even so, this circuit is simple to build, compact, relatively inexpensive, and provide a level of performance that will satisfy most of the needs of your car audio.

Car power amplifier circuit using Output Transistor C5100 / A1908. Power Output About 400W RMS at 8 Ohm. Power Supply need 32V DC Asymmetric, For car application you can adding inverter 12VDC symmetic to 32VDC asymmetric.

Q4___________________ MJE350
Q5___________________ 2SC3421
Q6___________________ 2SA1358
Q7___________________ C5100
Q8___________________ A1908

Note :There is NO SHORT CIRCUIT PROTECTION on amplifier circuit. The amp is designed to be used within a subwoofer or other speaker enclosure, so this power amp is matched for car subwoofer amplifier. A short circuit on the output signal will destroy the amplifier.The power dissipated is such that great care is needed with transistor mounting and cooler.

Simple 10W High Power LED Driver Circuit

This is my project for handmade flashlight when using 10W High Power LED voltage 12V DC. Indeed, by using this LED light produced is very bright. However, to use this LED requires a power of 10W and 12V stabilized voltage, so that LEDs are more durable long lasting without reducing the productivity of the light produced High Power LED's.

So it takes a LED driver circuit, precisely to control the voltage current and voltage itself. Here ne driver circuit is simple and easy to manufacture only need a few components that are easy to find in stores store and the price is very affordable. It also can use recycled components from the junk PSU.

For Installation, Install transistor with cooling, as well as its LED. See Tested Simple High Power LED Driver Video :

Note : Be careful with lights up current High Power LED, because LEDs also produce heat at the bottom, so do not touch it. Also On the LED front, not to knock, because it can damage the LED.

2800W High Power Amplifier Circuit

Mono high power amplifier circuit is actually  powerful , output about 1400 W, but if this high power amplifier circuit is doubled and you want to create stereo power amplifier, this high power amplifier circuit the necessary components and pcb requires two-fold. So if the stereo high power amplifier 2 X 1400W Power Output ( 2800W ). Power Amplifier Circuit Diagram is still less by looking at the circuit that was so below, the finished circuit has been added with a gains, using two JRC4558 IC  the picture ic where it can be seen below. For circuit buffers, drivers, and booster use multiple transistors and other components (can be seen listed component). And high power amplifier project that is so below is just part of the buffer and driver while the booster has not been made​​. For additional transistors in the booster or high power amplifier end scheme can be found Booster output power amplifier. For bass booster using this circuit :
