A question about diamond buffers

[darian]

Hello everyone,

Recently (since this morning actually) I got very interested in diamond buffers and found several schematics. I understand the principle for the Walt Jung version and some derived ones but not this one for which I post the schematic. I may be a dumb question but how is the second stage correctly polarised? To me it looks like a class B or even C stage... Probably I'm missing something in the design...

The Wat Jung design is limpid, with the emitor resistors on the first stage setting the second one in class A...

Sorry, I messed up.

Going to Solid state...
