I think you'll find schematics very hard to obtain, but if you contact
Peter Schillebeeckx at Soundfield (now TSL) -

Hello everyone! I'm new to this list, but not to Ambisonics
Good evening,
Learned a lot from this list by lurking and reading, thanks for all your great
knowledge; so now it’s time to delve into ambisonics myself.
Therefore I’m looking to purchase a used but good condition SPS422(B), so if
anyone has one for sale or any leads, feel free
to contact me.
