This simple mosfet power audio amplifier circuit, with TL071C and 2 MOSFETs (IRF9530 and IRF530) can deliver up to 45W on 8Ω speaker or 70W on 4Ω speaker. This schematic is based on Siliconix ...

Apart from the possibility of gate breakdown, which, in power MOSFETs, always occurs at less than the maker's quoted voltage, except at zero drain current, MOSFETs are quite robust devices, and the ...

Most discrete power MOSFETs are rated for 12 V, 25 V, 30 V, or even higher, so selecting a MOSFET with V DS suitable for testing low- to mid-voltage supplies isn’t difficult.

A further change is that the power amplifier MOSFET complement has been doubled (though headline power output is unchanged at 80 watts per channel), which combined with a change to the novel ...

When it comes to its power amplifiers, Goldmund doesn’t take a back seat to anyone. So far in 2024, we have reported on the Telos 690 Integrated Amplifier and 800 Stereo Power Amplifier that offer a ...

But it’s not only the price that sets this unit apart from the rest of the range. This is the first time PrimaLuna has stepped into hybrid amplification. In this case that means the preamp section ...
