The current started at a relatively low value around 1A in datahseet testand as the device heated up this was seen to rise. The lower impedance of the driver stage the better.
Transistor Q1 and Q2 forms the input differential pair and the constant current source circuit built around Q9 and Q10 sources 1mA.
I disconnected the irfp240 from mains quicker than the fuses. If you are using 2 similar amplifiers yes with proper insulating kits you can use provided the sink is sufficiently big to take care of the generated heat. Don’t run any signal wire close to a power supply wire or the power transformer.
Although the requirement for this is minimal the CD format is incapable of anything even approaching a square wave above a couple of kHzit has become an expectation that power amps should be able to reproduce perfect square waves at 10kHz as a minimum. Don’t add these yet!

Also note the capacitor in parallel with R7. Hi Chiliman the bridge rectifier should be capable 25amps. But if we use a matching tool, we will find that the gain varies considerably from the actual devices vs.
I use a k pot but when i turn it off i stil have sound in my speakers, a 1M ohm pot would be good or even it will be small? Make big traces on the PCB with decent sized spacing between other traces. Figure 6 – Normalised V th Vs. A few tens of millivolts irffp9240 gate voltage is the difference between acceptable quiescent current and overheating. It’s worth noting that the TO darasheet 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.
Instead I would like you to use separate filters and rectifier for each amplifier, you mount bridge datasheey and filter capacitors of the value shown in each circuit board.
Rather than increasing the safety margin, the larger device is more likely to fail if it is working well below the ‘inflection’ current in a linear circuit.
The amplifier has a low distortion of 0. Should V th fall by mV, Iq can only increase by mA. 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. If it is ok replace link with say 2k2 pot and set the current through the fuse for 50 to 60 mA. Can dis circuit wrk with bc?
This can range anywhere from Ohms up to perhaps 5k. It will be great if I get your valuable suggetions. This may include adding a class AB driver stage. If I power up six of these with the same power supply, what value should each rectifier diode have? This application note also mentions the possibility of a failure mode similar to second breakdown when operating switching MOSFETs as linear amplifiers. Reduce the fuse rating to mA. This must remain a very good reason to stay clear of these devices for audio, unless you are fully aware of the potential risks, and how to avoid them.

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. Hi Theofrastos K logarithmic control that should take care for volume problem at lower settings, do not use Lin controls. The graph was taken from the IRF data sheet, but has been colour coded to igfp9240 identification of each graph easier.
Does bass preamp will work like a filter?
A careful examination shows that the ‘inflection’ point is actually the region where the negative temperature coefficient of Datashedt GS exactly compensates for the positive temperature coefficient of R DS on. I have volt 3amp. It looks very simple, and includes the class AB driving stage to improve gate driving.
In an application note [ 1 ]OnSemi describe this transition as the ‘inflection’ point, and it is determined by V GSalthough it appears to be related more to the drain current than gate voltage. It may be possible to select the zeners to achieve basic current limiting, giving the amp some protection from overload conditions.
