Hi Niklas in the place of R8 put a link.
The graph was taken from the IRF data sheet, but has been colour coded to make identification of each graph easier. Only lateral MOSFETs provide a crossover point on their transfer characteristics that is low enough for linear operation.
I have transformer of 3 amp. The only way that you can be assured of safety is to keep the peak dissipation well below the claimed maximum, thus minimising the die temperature. You may also like: For some further reductions in distortion, the following work quite well: Finding the correct design parameters becomes more complex with non-linear devices.
Am I missing something or should the measurement be across just 1 x 0.
Can i use it as a subwoofr amp? Many fake lateral MOSFETs are re-badged vertical devices typically HEXFETsso source and drain are in the wrong places and the amp will provide close to a dead short across the power supply via the intrinsic body diodes.
Will the Irfp work instead of the in this circuit? From Advanced Power Devices, their application note [ 2 ] provides the graph shown in Figure 6.
Even this will not show the same effects as a true valve amp – the nature of the distortion components will almost certainly be different.

A class-A driver will work fine if you really want an electric heater, as you will see in the next calculation.
The use of source resistors to help force current sharing is essential, and these datasbeet be as high as practicable.
IRFP9240 – IRFP9240 P-Channel MOSFET Transistor
The current to reproduce a sinewave will be a bit lower, since it is a smooth curve, but this much headroom will drastically lower distortion. Resistors R3 and R2 sets the gain of the amplifier.
Do the tweeter have impedence? Thank you sir, god bless you. Likewise, the peak current should also be much lower than the rated maximum.
Adjusting the bias to 1 amp removes nearly all distortion, yet now we are approaching a heater If things are ok set the current as recommended, and connect 8 ohms speaker and try. The positive jrfp9240 of R DS on is insignificant dataheet the current levels needed for setting quiescent current accurately.
Im also planing to do a LED spectrum analyser and digital volume controls with remote. Preset R8 can be used for adjusting the quiescent current of the amplifier. It’s very daasheet compared to amps with multiple LTP stages. Figure 6 – Normalised V th Vs. Thanks for the help.

There is also the possibility of a failure mode very similar to second breakdown when HEXFETs used in linear circuits, where V GS is usually well below the inflection point. Also note that this amp was built on a breadboard. While the graph might seem to indicate that the effect will be greatly exaggerated at lower gate voltages and drain-source current, the initial tests that I did indicate that the effect is roughly similar. To illustrate this, Figure 5 shows the graph from the IRF data sheet, and although it does not continue down to the levels we are interested in, the trend is clearly visible.
Requests for component values will not be fulfilled. I have check voltage across drain to source of Q8 n Q7 Q7 drain to source and drain to gate is 37 volts Q8 drain to source and drain to gate is 71 volts.
This amp will work, but you have to add a filter circuit at the input. The resistors seems to be fine.
Using HEXFETs in High Fidelity Audio
Use a single transformer may be torroid one capable of 20amps capacity. Bandwidth is too short how can i increase it i need at least 15KHz. This is why we cannot practically use a class A driver, unless, of course we use one pair of output devices.
