Has anyone seen this bridge application in EDN Online?

Looks good, though, this is a good example of how good/wrong some times the recommended schematics/ap-notes are. I think 5 dots are missing from the final schematic (Fig. 8). Can you guess which ones?

Stand corrected. Only four dots.

in parallel with the 12pF caps. I found an error in an IR app note for some HexFets and wrote them telling them about it and my local supplier gave me 10 of each n and p channels for free!!

Aren't there dots missing between the 10k and the .25 resistors and immediately after the input?

Of course, in spite of the title of this thread, this isn't a bridge circuit at all, even with the missing dots.

A cursory reading of the text or any thought about the circuit makes it clear that this is a parallel amp configuration.

Is bridging different from an amp to another ? I have to bridge my marantz...
