    I've been asked by someone, quoted funny money for a
    replacement B&O cartridge, to sort out something cheaper.
    Looking in a number of Bang & Olufsen Beogram manuals they
    never seem to specify whether MM or MC.
    Due to small physical size and their stock numbers always seem
    to be MMC.... i assume Moving Magnet Cartridge.
    I am aware of MM/MC selection switches on phono section of amps
    but is there a significant impedance or level or equalisation requirement
    that cannot be accommodated by volume & tone controls?
    Obviously a large bog standard moving coil cartridge will look
    ugly, which he is aware, and I'll have to mount it on the tone-arm above and
    set
    back from the end of the B&O arm and add counter-balancing
    weight at other end. But will it function well enough for
    music non-purist ? Any ideas on fairing/ masking so as
    to disguise the bulky and bodged appearance. ?

    Why would you care? I haven't ever seen a MC cart IIRC.
    None I can imagine.
    God's teeth don't do that. He needs to bite the bullet and buy the real
    thing - look on eBay, maybe he'll get lucky.
