1) Because the inductor theoretically can swing twice the rail voltage.
2) Because the music is not a square, but a bunch of sine's, which it has no problems supplying with great force. The square shows more about rise time, than freq. response.

You could give the Zen 7 article a read, to get a general idea of what we have been up to.

If you got the cash for making such an amp, I sure would recommend giving it a shot.
Lot's of work, compared to the CCS version, but worth every minute/$$$.

I'm now starting on a CViller F5 with "mods" .😉 is there a good/better/best approach with the inductor , as to type , size etc? .......
naah ...... that's amp for sissies
My inductors are bigger than yours!
And like if that isn't enough, my dad is fatter than your dad 😀

Good/better= huge iron core inductor=huge transformer=2kVA transformer.
Best= even bigger air core bifilar inductor.
Even better= 2 friends to help you move any of the above 😎

EDIT: F5 with mods?

The big iron is more a matter of avoiding saturation, so according to my experience, we are talking at least a 1kVA transformer, and preferably more.
The air core is a lot easier to deal with, regarding saturation, as there is no such thing.
For an air core, you can get away with 2 x 80mH. Now that doesn't sound all that scary, but you also need low DCR, which makes it somewhat more problematic.
I made mine of 12 gauge copper wire, which gives a DCR of 2R4 per winding, as I recall.
What I do recall very clearly, is the weight of them: ~22kg a piece!

Sure, you're right in both aspects. Much cheaper actually.
......but you won't get the same result.

boyz - I think that this thread isn't most appropriate for all little details about Magura's amps ;
glimpse here and there , as part of event ..... but theory of operation ........ better to use other thread ....

OK,
Where else can i get both Magura's and your attn without the traffic.. 🙂
Our discussion is just an extension of his DIY event. If he was closer, for sure I would be in Denmark nagging him with questions .. 😀

you can read from start ....... and ask what you need , when you feel bored enough
I find that the music has stronger dynamics, more "spring" in the notes. It's actually kind of spooky the sounds that you get during the quiet passages. Without the inductor, I think the music sounds very smooth, but flat--like warm, non-carbonated beer. 😉
