RF modulator pinout

    Hello,

    I am looking for pinouts of an RF modulator made by Mitsumi,
    MDF33-UE4102.

    It has 6 pins, named V, G, A, N, Bm, Bb (plus the internal RCA).

    My guess is that V = Video IN, G = Ground, A = Audio IN, N = No
    Connection and that Bx is power, but what does M and B stand for on the
    B-connectors?

    Thanks,
    Robert

    AFAICT ...

    Bm = MOD+B = Modulator Section B+ = +5V

    Bb = BST+B = Booster section B+ = +5V

    The "UE" in the part number may indicate that it is for the German
    market.
