Monoblock Amplifier circuit TDA7294 based on an article entitled “Improvement of the power amplifier IC TDA7294 Journal based on the radio schematic. This amplifier has a single car has a sufficiently high reliability, high capacity, high-quality bass. Monoblock power amplifier circuit is shown above. The only difference from the original circuit in the output transistor with a better replacement.
The circuit shown in the figure, is base the LM1875 chip which has a soft, low distortion (0.015%) when the current is the style of the team is small enough, popular DIY chip amp. Power transistor control output with a more powerful sound warm and soft on the Toshiba power transistor 2SA1943, 2SC5200 (VCM = 180 V, 12 A = ICM, PCM ? 120W, fT = 30 MHz).
Who should be on the lookout for quality amplifiers for their sound systems in any case, shoulder to shoulder with the DX-Series of high-quality amplifiers. DX-amplifiers are another kicker of skills capable of high-level sound quality and crystal clear clean audio to offer.
A common problem for most amps today is the noise, especially if they worked himself pretty bad. But DX amps do not have this option in their menu, they are suitable for Fail-Safe Integration Technology that cleans the noise can sound waves, spikes and also reduce electrical noise in the sound system.
The original Monster Jean Hiraga 8W class A amp, I wanted “The Monster” big brother build “20W Class A” amplifiers. After reading the construction, testing of Jean Hiraga 20W class A amplifier, and copies of old French magazine “L’Audiophile” I was interested to hear for me, as the monster sound like the big brother. I decided to build my latest version on the basis that I find as a “Super Class A 30W”
The original of Jean Hiraga Super Class A 30W amplifier circuit diagram and PCBs
In the past, I showed the original layout in the magazine article and the original driver transistors. However, due to the unavailability of the power transistors of origin, I opted for a more robust amp with Toshiba 2SA1943 and 2SC5200 pairs of complementary transistors. This change allows me to transistor voltage rail, which can increase the amplifiers deliver more power. The schematic for my version of Super Class-A, Jean Hiraga 30W amplifier.
Toshiba 2SC5200/2SA1943 on the stereo amp tube edge. Description of the circuit. The ower amplifier uses a typical symmetric OCL Class AB output, has the power, efficiency, quality and beauty are high / frequency / bass imported good, rational circuit design, original Toshiba tube on the accuracy and Taiwan high 0.5 to 1% W metal film resistor, so that this amp has a very good performance.
The compact size of the PCB, and integrated power rectifier circuit UPC1237 fully functional protective case, components are arranged neatly in a compact, whether visual or material, all the products say passionate.
