This is a mono 100-watt transistor amplifier circuit diagram. this circuit diagram can make 100 watts using one pair of transistors

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.

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.

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…

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 […]

The 2N3055 power amplifier circuit is an excellent choice for anyone looking to build a simple and reliable amplifier circuit.

This is a simple chassis using just 4 aluminum panels and 2 heatsinks. Designed around dimensions to tightly pack in a LM3886 chip amp kit. The top and bottom panels sit in ridges cut into the heatsinks with a table saw, and then the front and back panels just bolt into the end fins. Rear panel fixings are held with M3 nut and bolts, and panels that join to the heatsinks are held by M4 bolts tapped directly into the heatsinks so no additional brackets are required. Heatsinks are 75 x 160 x…
