just an example schematic
i have the audio drivers circle in red
example bd134 pnp 1.5 amps 80v 12.5 watts
bd139 npn 1.5 amps 80v 12.5 watts
mje15034npn 4amp 350v 50watts
mje15035pnp 4amp 350v 50watts

For the schematic and outputs shown I'd just stick with the MJE15034/5 drivers and either BD139/140 or MJE340/350.
re VAS, I was looking at these Fairchild transistors -

What do you people think? They look like good VAS and predrivers in a triple darlington output stage to me.
