In this article, we will discuss the working principle and specifications of the Subwoofer Amplifier Circuit TDA2030, as well as the accompanying BD711 and BD712 transistors used in its implementation. The TDA2030 amplifier chipset provides an excellent solution for constructing a subwoofer amplifier circuit.

The ML-2 is a massive class A mono amplifier. It's output power is often advertised to be 25 watts but it's actually more than that, maybe up to 100W. With its class A design that means it's large, heavy, it runs hot and it's power hungry (even when idle). It'll happily suck 400W from mains (double that if your system is stereo !). The ML-2 was used in the HQD system. Since the HQD is based on Quad ESL-57 panels, the power of the amplifier had to be low but it should be able to drive low…

When it comes to sound quality, newest isn't always best. Paul Rigby looks at some of the vintage amplifiers that will bring out the best in your records.

DIY Class D Audio Amplifier circuit diagram. this is a circuit diagram. It can make 300 watts using 50-0-50 voltage.

Audio Amplifiers are being used for decades. The main function of an audio amplifier is to reproduce the input audio signal at sound producing systems like speakers with desired volume and power levels. The frequency range of audio signals is between 20Hz and 20,000Hz. Hence, the audio amplifier must have good frequency response over the […]

Sansui AU-717 Integrated Amplifier So here we've got a incredibly clean and pristine AU-717 integrated amp. Theres quite a few thing I like about the AU-717. The layout is very clean, they used proper shielding over all AF sections that we like to see, the shielding itself is attractive ,matching the clean black gloss finish elsewhere. The PCB locations and mounting make for some fairly quick work, especially when pulling the driver sections. I should note to properly pull the protection/PS…

More than eleven years after its publication on this website and an ever increasing success, the 3 - 5W Class-A Audio Amplifier has undergone some small modifications (the addition of R1, Q2, R6 and the substitution of Q4 with a Darlington transistor) capable of producing a major improvement.
