Eliminating the OPT: impedance matching

Giaime · 23rd July 2006, 04:16 PM

Hello everybody.

It's hot here, so we could start a very technical thread.

I've recently came across this amp manufacturer, and I got interested in the technology partially explained in their white papers, here and here.

What do you think of this? Could someone explain me how to practically to this? I don't think it's a class D amp with tubes, so with the output tubes amplifying the pulse width modulated signal. I think there's sand-state stuff, but how to "adapt" impedance?

Of course one could add a simple linear power buffer after the output tubes, but that's surely not the case. How?

I'm interested in tubes mixed with brand new technologies

David Berning's stuff is discussed here a fair bit. There are some threads on what you are discussing:

ZOTL and ferrites

Thank you very much Leadbelly.

But I can't open the PDF linked in the first post of the thread you linked, it gives me errors. That's very bad since I've been able to find only this description without drawings.

Thank you,

I tried that link but it still doesn't work. It appears to be an Acrobat Reader's problem, so I'm now downloading the lastest version to see if it works.
