Please visit this page for specific instructions for obtaining Crown factory service. You can use the Combo connector as an input, and the Barrier Block connector of the same channel as an output to another amp channel. The K Series amplifiers have a "Y input" switch that internally connects both channel inputs. The CP has barrier block input connectors, so the input signals can easily be jumped from one channel to another. Design features of the amplifier, including power supply design and transformer size, partially determine maximum peak inrush current for a given amplifier. In addition, the external factors of AC mains voltage and impedance vary greatly making exact values difficult to determine.

TIP and are complementary Darlington pair transistors which can handle 5 A current and V ,famous for their ruggedness. This circuit is designed so rugged that this can be assembled even on a perf board or even by pin to pin soldering. You must try this circuit. Its working great! The preamplifier section of this circuit is based around Q4 and Q5 which forms a differential amplifier. The use of a differential amplifier in the input stage reduces noise and also provides a means for applying negative feedback.

Thus overall performance of the amplifier is improved. Input signal is applied to the base of Q5 through the DC decoupling capacitor C2. Feedback voltage is applied to the base of Q4 from the junction of 0. A complementary Class AB push-pull stage is built around the transistors Q1 and Q2 for driving the loud speaker. Transistor Q3 drives the push-pull pair and its base is directly coupled to the collector of Q5.

The aim is to emulate an infinite impedance theoretically increasing the common mode rejection ratio to infinity? I did some reseach and what I learnt so far corroborates my impression that this circuit is well designed and worthy of a try.

I also think, using PNP transistors for a differential input is quite uncommon today. Naturally, Q3 has been replaced by a PNP transistor. My problem is switch on the power supply ,I heard the sound on the speaker is like feedback between the mic and speaker…. Noise is removed by replacing ohms resistor with ohms resistor.

Hey guys have you already tried the PCB design of this schematic by jspayne? If you give it gives w. For w you need another circuit. In one of the comments Seetharaman you said uf for filter!! But i couldnt get tip could u pls tell me which i can use as a replacemant, and also the 30 0 30v transformer is expensive here, is there anyway i can use the cheaper one… And again the 10k potientiometer how do i connect it to the circuit.

Chris if you read past comments there are others who found alternative transistors and regaring volume pot is said to put it in series with input. You must replace bc transistors before using this supply. Maximum voltage that bc can bear is 60v so search for high voltage transistors in place of bc….

This has been recurring. Matti it seems that you have a short somewhere if the lines are burning. Try to add a fuse atleast the fuse burns until you find the problem. Hi sir, I did this amp perfectly and also done w sub amp. IAM Living in a villege In my area, fm signals not clear. Sir please suggest me a good fm anteena booster ckt. Please help me sir.

If you search for "amplifier" on the Internet, you will get results for many web sites about audio power amplifier. But the "amplifier" itself is not just for audio. The device that amplifies something is called an amplifier. Of course, in the electrical circuit, including audio power amplifier, the various signals are exchanged as electrical signals. So, the amplifier is for amplifying the signal flowing in the electric circuit, and it amplifies the input current or voltage. It operates amplifying the electric signal output from the various sensor and making it easy to perform analog-to-digital conversion. An amplifier is a representative of analog circuits, and it is so central that there is nothing if the amplifiers are removed from the analog circuits.

Discover everything you need to know about circuit wiring, breakers and fuses, amps and watts, and more. The first step in understanding your home's circuits is to know how basic electricity works.
