Thanks PD, I'm trying to figure this one out.
So here's my initial thoughts - are they reasonable?
Build the two pairs of two stages together on one board. Use local regulators (TeddyRegs or is a simple LM317/337 setup good enough?) to supply the appropriate voltage to each stage - possibly even build them on to the board.
Power it with a single unregulated linear 30v supply rail from a SNAPS or a printer power supply.

I signed an undertaking not to disclose the original to competitors when I worked for Maclaren. [/url]
I may have missed some opportunities, but I could not get it to fit a straight one sided board - so had to add a couple of links to carry power or ground across a few signal tracks, since I don't fancy trying to make 2 layer boards by hand!
I'll probably try etching a test board this week.
PD - let me know if this is not OK by you, in which case you have my apologies
