Richard;
Fisher changed their MPX design mid way through the MPX100 production. They switched from a less effective circuit to the MPX topology pioneered and first used by Scott. The Fisher design is not an exact copy of the Scott, but is quite similar overall. They both use the same type of 8 diode switching circuit that eventually became the standard for all the better tube MPX decoder designs.
