Thanks Nelson, I can't wait! You can't have too many excellent crossovers after all...
The funny thing is last week when I ordered a Mean Well 24V power supply from Mouser for my H2, I thought to myself, "I should probably order a couple more of these."
I should've listened to myself.

wait for Pa's schematic , then introduce bipolar supply, taking all Vref points to GND
remove interstage coupling caps

There are only input and output coupling caps, no "interstage"
And how's about B5?
Isn’t that essentially what we already have in the diyAudio Store.

Aimed at the LX-mini but very versatile.

me dunno
that's what Son of Gustav presumed ....

Doesn't look as versatile to play with various drivers as the B5 would be. I could be wrong but it looks like component values need to be changed to alter the crossover. With the the B5 you flick switches.
I'd be keen to see a DIY B5.
I tried to reverse engineer the B4. My guess is attached. The Rs have values ", 2R, 4R, 8R, ...
For the LP part of the B4 crossover, opening all DIP-switches will open R9 - R12 (see attachment). This means no signal will reach the inputs of U5 and U6. (Likewise, opening R1 - R4 will the audio straight to the positive inputs of U1 and U2. I guess maybe the gates are grounded via 1Meg?)
