N-Channel mosfet amplifier schematic needed

[gearheaddruid]

class d amps.

I have not had the chance to listen to any of the newest generation of class d amps. I had felt in the past they were great for subwoofers but found them harsh on the mids/highs. I am sure the technology has come a long way.
But like old musclecars, there is a certain romance involved with large toroids, over the top heatsinks, and banks of large soup can sized filter caps. I am starting to experiment with class d but will still have my boat anchor of aluminum fins and copper to look good and get driven hard every now and then!
One more note, unless you are driving a load bank with it, a class d does not help warm the lab on cold mornings!

n channel n channel

hi..is there any good n channel amp? my friend tried many n channel amps but he couldnt work well..it starts to burn after 15 minutes..he built many amps but he didnt built a stable and good quality n channel amp..will you give a best and stable n channel amp schematic?i wanna try too..i bought nx150 pcbs but they didnt arrive yet..i want to built a nx150 amp with vertical mosfets..please give us some working schematics..thanks

N-Channel mosfet amplifier schematic IRFP240, irfp250

But is that REALLY the case? Are those MOSFETs not actually the standard type for that kind i.e. a number of separate power chips in one package and thus really more than one MOSFET and the statement about using one single MOSFET only marketing? I thought they were using these:

Can someone please send me N-channel mosfet amp circuit between 100w and 300w.I realy need one for my PA Since i have a boxfull of N-chanel mosfets.Thanx in advance.

Search for "legend stagemaster" or "quasor". Dr. Borivoje Jagodic designed it.

What quality level are you looking for?

Hifi or PA?

How much power is needed?

I intend to publish a new N-channel design shortly.

I happens that Zeta 2 amp once public on Olive audio was the second amp i ever built and the most successful diy amp based on fet transistors i ever tried and evaluated.In my opinion it is the best class ab Fet design i ever saw and it is a pity that it isn't public anymore. Would you, please make it public and available for everybody ? Of course i could publish it myself, but i know that it was your will to remove its schematic from here and everywhere else. I personally prefer its output be rebuilt with BJT transistors , but i think that its input +vas stage is the best choice for high power class ab diy . Even in its original shape it was the most stable amp i ever built or seen. Not all of us are accustomed with class d diy and design. It might look like a thing of the past for you so why not just make it available for everybody?

Zeta 2 is already a 17 years old project...can it be made public?
