It is claimed to be ‘insignificant’, and for switching applications this is true. In many cases, the lowest heat output possible is highly desirable, and HEXFETs are simply unsuited to any application where very low Iq is desirable or necessary.

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.

While there appear to be many advantages to their use over BJTs, HEXFETs may often suffer from exactly the same problems – thermal runaway and a failure mode that is suspiciously similar to second breakdown.

Hi Chiliman the bridge rectifier should be capable 25amps. Power amplification stage based on Q7 and Q8 which operates in the class AB mode. For the design of the amplifier, I will assume a single LTP input stage.

Should V th fall by mV, Iq can only increase by mA. Even this will not show the same effects as a true valve amp – the nature of the distortion components will almost certainly be different.

Please check and correct and proceed as above. Use a single transformer may be torroid one capable of 20amps capacity. Preset R1 is used for adjusting the voltage at the output of the amplifier. What power will get when i connect 10inch 4ohm subwoofr?


That is why we need to buy a few extra and match them together. Something must be terribly wrong with my circuit. C1 is used to take care of HF decoupling, as C2 is wound capacitor with inductive componunt and for LF decoupling. A basic dual power supply is used for the amplifier circuit. I will make a pbc for this circuit if u want it just ask, but has anyone considered using Irfp for this circuit instead?

We want to measure what the load is doing, not what it should be doing. The spec is given below, also I have some doubts regarding the project. It can also cause major problems in switching circuits, but that’s another topic altogether and will not be covered here.

From Advanced Power Devices, their application note [ 2 ] provides the graph shown in Figure 6. Well, that is the easy route to take for designing an output stage.

This give a clue about your problem. I suggest that high voltage, relatively low current devices are preferable to the reverse, as they will have an inherently higher R DS onand therefore a lower inflection point.

The bandwidth is 3,6Hz to Try this W Hi-Fi mosfet Amplifier http: I think that it will do the job, but I want to be sure.

There is no evidence of ‘notch’ distortion or any other nasty odd harmonic, only a ‘nice’ second harmonic added in. It is a temperature compensated constant current mirror.

That it is possible to build a valve amp to a high specification is not in doubt, but they tend to be complex and expensive. Can i use it as a subwoofr amp? Hi Harry can be used. I’ve tested an amplifier that used them, and they perform well enough, but it’s doubtful that there was really any advantage over using bipolar output transistors other than cost.


I disconnected the circuit from mains quicker than the fuses. To balance out the nonlinear curve, we can simply cut if off where it seems too bad by using bias. This application note also mentions the possibility of a failure mode similar to second breakdown when operating switching MOSFETs as linear amplifiers.

And many pages from ESP.

It’s worth noting that the TO package is useless regardless of what’s inside for getting rid of any more than about 20W worth of heat, unless extraordinary care is taken with mounting.

Of course R17 must be ohm. Is good circuit have tested it and it works well the circuit is better for very high voltage. It can work with 4 ohms speaker delivering around watts.

I think preamp will just only increase the voltage level of the input signal, but when we split a signal into two actually the current is divided into two. I need watts rms amplifier circuit diagram. If driven incorrectly, they show high distortion levels, especially vertical types – most commonly these days, HEXFETs. This does not mean use an inadequate heatsink, but the bias between devices should be a bit more than many are used to.

Filter capacitors C8 and C9 must be at least uF, higher the value lesser the ripple. I have volt 3amp.
