The schematic is included on the instruction CD that comes with a kit. I don't know if it can be given out without purchase of the kit so I would get in touch with Doc B. here or at the Bottlehead forums to ask him about it.

It is very similar to the VanWarde OTL on headwize, but with cathode LED's in the gain stage.

Your best bet is to contact Bottlehead directly.  They have a pretty, good description of the circuit on their website.
