here, not to hijack the original thread.

No output coil, you are right. I will make more measurements of this kind with suggested load later, as I am pretty busy right now. I promise to return to these mesurements. As a reminder, the original response into 4 ohm.

Uses massive feedback, though. And to add insult to injury, I can't use it to heat my house .

3V/div vertical, in all the images shown. If there is 30V/d somewhere, it is a forgotten probe scale factor.
