5W MOSFET Class-A  Amplifier Single Ended Project

For a long time I was thinking about making myself a good class a amp, next time after you fix the mechanical failure before the truck and the min, I said something like Pila access your listening pleasure and decided to make this single-ended amplifier 5w amplifier, a long time ago when I was really satisfied me that this was the experimental sound of the amp.

As a single-ended amplifier circuit is very successful, 4-5 m is a square room sound power
enough, I think, especially with a good pair of speakers ‘ rest and she’il (high-sensitivity 90dB or more) can be very, very good efficiency.

A single-ended amplifier circuit is very simple, but really want a quality work, as much as I can, I tried not to compromise on quality.I would definitely recommend a similar circuit for those who do.

Let’s start from the first open-circuit, the circuit is pretty simple, there’s a supply, 24v

2SK1058 MOSFET Class-A Amplifier (ZCA)

Class-A-2SK1058-MOSFET-Amplifier-ZCA

I used a transformer circuit around 100w 2 x 18v AC outputs (the transformer wraps master is really doing a good job, because the transformer with the transformer for the ones who need me, I am the workmanship.

I think the most important part after the transformer feeding, this circuit prototype work I did when I used a simple feeding, leaving severe hum (noise).Asıl feed 20,000 Uf capacitor with a coil 10MH, landed very, very low noise levels.

The circuit is a class a operation, naturally comes with heat, especially if the circuit
lot 15 Ohm resistor that enables the flow of warm, therefore, must be connected to a refrigerant pressure.

    PIC16f88 Humidity Control Circuit SHT11

    Seenserion company produces heat and moisture sensor SHT11 humidity measurement and control circuit is made with. The circuit can be used in many different purposes. For example, agricultural irrigation, soil humidity, according to the soil to make our daily life, environment or watering the moisture to check (under normal circumstances, the current environment has to be 45%-55% humidity)

    Summary; Mucha Elijah that moisture, humidity set on while the relay is open. The humidity value falls below the value in our draws and arranged irrigation starts.

    Hi. Like your amplifier build. Looks really nice. I built one too. Sounds really good.
