This audio amplifier circuit delivers up to 200 W of top-class quality for loudspeaker from 4 to 16 ohm. Operating voltage is between 24 and 36 V, max 5 A. The frequency response is from 20 to 20000 ...

Connect Resistor with Circuit - To make this powerful amplifier circuit, 1st we connect resistor with the transistor. We connect 1k resistor with "Base" and "Collector" leg of C5198 transistor. Then ...

In the simple circuit shown in Figure 9.9 (the case shown is for an NPN transistor, but a virtually identical circuit, but with negative supply rails, could be made with a similar PNP transistor), the ...

A simple circuit modification can effectively reduce temperature-induced noise for a JFET-based amplifier at a reasonable ...

The circuit’s phase shifts — thanks to resonance and the transistor’s Miller capacitance — keep it humming smoothly. But this circuit isn’t just for LEDs. Add a couple of diodes and capacitors, and it ...

This paper describes a voltage controlled amplifier with linearized response to the controlling voltage and discusses its harmonic distortion. As a controlling element, a JFET transistor has been ...

Back in the '60s, there was an intriguing circuit article titled "Starved-Circuit Amplifier" published in Popular Electronics magazine. It used a sharp cut-off pentode with a 3-MO load resistor ...

So, all dead transistors replaced with appropriate equivalents, and the amp was reborn. Success, and very much worth the effort! We’ve covered a lot of amplifiers here in the past.
