"Never, repeat never, to me does not make that model did not fit the facts, must I know what I choose and in the production account."
If I said model an OPA604 set up for a gain of 10 and show me the square wave response at 10 volts pk pk @ 50 khz, and I went and built that circuit on a sensible PCB I guarantee the real world result would be different.

When you are designing operational amplifiers, you have parasitic capacity, you have a parasitic, phantom transistor, etc ...
When you design a fast amplifier, without local feedback, you have a high frequency transformers, etc ...
As I wrote it a practice first simulate and then implement the same. No trial and error. That time is gone.
I note that this thread is about something else, let's go back
Please.

Do I please the phase shift output signal, and Do not change deliberately and continuously from a thread.
Federmann, you wanted examples.
I simulated one of my amp and HQQF.
What would you read from coffee sediment ?
Such as distortion, slew rate, etc., load is 4R

green - HQQF, red - amp5z

Still you are complaining about the diversity of models and specific elements. Why did you proof of the result of simulation? Excuse? Could you show the measurement and simulation at full power, then compare and look for differences.
I have praised the outcome, but I know that for a large voltage is different. Simulation also come worse. Real transistor is better. Lissoujuss shape tells a lot.
Instead of holding the thread, still out of thread.
Please speak only about the graph. Everything else is off-topic.
Thank you very much.
PMA and Upupa Epops, I will make Hugo's suggestion an official directive- you've made your points, continuing to repeat them over and over and slipping in personal invective is not tolerable. If you want to argue on a different forum, go right ahead. Not here. And dragging in disputes from other forums is doubleplus ungood. Binning for a longer term than your last one will be the next action.
Thank you for your constructive contribution.
Both amps look very similar. But I see a big difference, HQQF gives 1kW, but amp5z only 250W. Judge for yourself which is better.
