Sorry, nevermind, the M-200 was not included in that link I previously posted. Poking around the internet I found hifiengine has the schematics for the EX442 and a note saying the M-200 is the same as the EX-442 with only the left CH pre-driver loaded and the output boards strapped in parallel. The Dual Mono power supply is also strapped in parallel.
I also own schematics for other B&K, but not for the M-200. Sorry.
