        Abstract: We report conductance measurements on multiwall carbon
        nanotubes in parallel and perpendicular magnetic field. A gate
        electrode with large capacitance is used to considerably vary the
        nanotube Fermi level. This enables us to search for signatures of
        the unique electronic band structure of the nanotubes in the
        regime of diffusive quantum transport. We find an unusual
        quenching of the magneto-conductance and the zero bias anomaly in
        the differential conductance at certain gate voltages, which can
        be linked to the onset of quasi-one-dimensional subbands.
