I just said analog gurus for lack of a better words 😉 Just some experienced analog designer(s) or similar. My own knowledge and experience in the field of electronics is very limited. I also don't know who is behind the forum accounts most of the time, the number of familiar faces and names keeps growing but half of the time I have no clue who I am talking to.
I just noticed there now exists a wikipedia article about diamond buffers. It was created in June of this year by someone who apparently put quite some work into it.
What I had in mind was something similar but much more detailed in some aspects, with the focus on topologies that can actually be implemented with readily available discrete semiconductors. Of course the individual parts would be kept rather short, no super deep dives, no explanations of really basic stuff. It should be assumed that the reader has basic knowledge and the ability to read up on some stuff. The interesting part would obviously be simulations and potential measurements. I thought that we could maybe agree on a set of exemplary use cases with adequate specifications, test signals/loads and boundary conditions, as well as a selection of commonly available transistors and models to be used for the comparative analysis. Quite a few interesting parts sadly have gone EOL recently or are in the process of going EOL...

Hi guys,
Do you have or know a high current diamond buffer type? I would like to build a 100W+ amplifier in this composition wich diamond buffer.
Thank you in advence

Thank you dreamth, but I am a little bit bad searcher. I don't find the right schematic because none of the above include the exact part types or high current parts. If you or anybody have a tried schema, please share with me.

LM,
This amp with Wilson mirror - do you have some more info about it? An article or something...
It looks very interesting..
Diamond Buffer with CFP

It's been a long time since i last saw Roman's favourite amp. Perhaps no longer favourite. Looked uncompromising to me at at the time, but not so sure about that today. With the fake bipolar output supply and the really basic supply for the tubez. What, not even a choke?
And a quote from Charly Hansen seems appropriate, seeing the weird biasing arrangement here:
"What is different about the diamond buffer from a typical output stage is that after the signal has been split into two halves to send to each output device, is that the two half signals are rejoined at ONE single point. There is NOTHING in between these two half signals. A conventional output stage always has something in between the two inputs of the two half-output stages before they are recombined. Typically it is a bias circuit of some sort that sets the idling current in the output devices. but there is always something there."
