OK :
if it is so in the simulation not post the same project not a project that was created by myself, but I doing the pcbs and do not venture on projects that are doubtful and were only simulated in PC programs but this project can say it has quality and has been tested in practice most successful myself am riding my board that is in the photo.
The project is posted and whoever wants to can ride do not force anyone to ride anything but what I can do is share my friend's project, many IRAM criticize the project but it is easy for those who do not ride and does not believe in the simulation program.
Who have questions I can answer the I am available and those that do not know I look to the creator of the project.
That Jesus bless you all and good mounts

An externally hosted image should be here but it was not working when we last tested it.
Transistor information>
good friend I'm not going to hold the reports that are not related to the amplifier not to harm the site and put in question the operation of the
600 W into 2 ohms with 5 mA of VAS current and an EF2 output stage? How's that supposed to work out?
I mean, asking for a reliable total current gain of 10000 from an EF2 output seems like a bit of a stretch.
Motorola transistors do not exist any more try ON semi
Datasheet like the above is what you need to use them properly

Friend look at this video you can see that it was using the 220R resistor test to show what happens to the waveform, this resistor already questioned him but he's just right was so qeu was simulated in practice can watch the video so be sorry Portuguese in the narrative
monitor more on the amplifier in our Electronics Silveira forum.
I would love to someone who rode to exchange some ideas and post pictures, but so far only seen people criticize and judge the project here.
different from what we do in the forum is elegiar and assemble to take proof of quality

2 ohms / +75 -75VCC = 600W, THD em 0,0029%
2 ohms / +70 -70VCC = 540W, THD em 0,0058%
4 ohms / +75 -75VCC = 470W, THD em 0,0023%
4 ohms / +70 -70VCC = 400W, THD em 0,0022%
8 ohms / +75 -75VCC = 300W, THD em 0,0042%
8 ohms / +70 -70VCC = 240W, THD em 0,0012%
ADJUST BIAS:
Mount the set with the bias trimpot COMPLETELY CLOSED (0 ohms), in which the the quiescent current is set with at LEAST. Open slowly adjust, about 180mA by rail.

That was probably exactly why such a design was posted in this forum and has a name "Debunker". Let's be debunked and be happy😀
Friend is possible but this is the debunker 2 has already been made a version that was questioned before, 500W, and questioned but when it was posted Video proving one 535W power nobody said nothing more.
