sold out, gone forever? we may get one or two in from time to time.

CAUTION/WARNING! There are absolutely NO returns on this obsolete FACTORY SEALED PRODUCT.

Yes like everyone else we have just a few of these left. They are B&O factory sealed! The MMC4 is a function replacement for the MMC1 MMC2 MMC3 and MMC5 (MMC1 is top of the line, MMC5 is bottom of the line.) The needle on your existing cartridge is not user replaceable. Keep your old one in case we ever find a good tip replacement service.
This wonderful cartridge will work in any of the following Bang & Olufsen models:
