The 950 was fitted as general rule with MC boards.
MC boards were the standard (EMT did not produce any MM cartridges)
Clients that used MM boards used various MM cartridge makes (various solutions to adapt load to specifics)
The 950's that host MM boards are of a lesser value than those with the MC ones. Often studios sold their 950s without the MC board replacing it with MM one, keeping the MC ones...
For the "reference" points:
The equalizer amplifier consists of 3 circuit boards:
Amplifier supply board 7 950 037
Equalizer amplifier 7 950 038 / 088
Line amplifier 7 950 039
The version of the equalizer amplifier (038 or 088) depends on the pick up to be used:
MC: 7 950 038 version is equipped with two input transformers (haufe) to be used with MC pick ups (EMT T-series).
MM: 7 950 088 This version has no transformers, input impedance 47 kOhms. It is to be used with MM pick ups.
As we all know the boards are interchangable without need of any adjustment short of VTA/VTF...as the MM carts may not have the same height/weight as the T range (all same height and weight).
All fun!
