Reel deep thoughts...
Good luck.
I don’t recall what kind of detail I put in my M-520 thread about getting channel modules out, but, from memory, there are screws on the dark brown horizontal panel in front of the VU meters, right behind the channel modules...remove those. That will allow you to tip the meter bridge and backplane back like you’re opening the hood of a Corvette as one unit exposing the interior of the jack panel and all the wiring from the jack panel to the modules. When you tip that back you’ll expose two screws for each module. Remove those. Then there are two more screws at the front of each module under the trim strip that is in between the upholstered wrist rest and the modules. Remove that trim strip and you’ll see the other screws. Once the 4 screws per module are out the entire module can be removed in its entirety after you unplug everything that goes from the module to the jack panel and the motherboard. Once you tip the meter bridge back it will make more sense.
