Links to JBL T-circuit???

Hi,

Prof. Leach has a good description on his use of the JBL T-circuit on http://users.ece.gatech.edu/~mleach/lowtim/output.html, though I wonder if anyone have more links to this type of output stage?

I'm trying really hard to "fully" understand the Leach-amp and I'd like some more theory to dig into.

What I've came to realize/understand is that it is really important to tune the crossover distortion in any kind of A/B stage, but in a T-circuit this is somehow a little bit easier to manage than in other solutions.

Am I just inexperienced and plain stupid, or am I on the right track?

Best regards,
