I managed to get a good condition beogram, but am now slightly concerned.

The beogram is branded Beogram RX, athough is fitted with 2 phono plugs doesn't correspond to the product desription here. It looks exactly the same as the Beogram 1700. I need a new stylus/cartridge and don't know which is the correct one to buy. The MMC 20 series or the MMC 1-5 series - can anyone help? 

Very short lived deck - it replaced the 1800. It takes the MMC1-5 cartridge. RCA plugs were standard. We could actually do with a good picture of one of these for Beocentral! If you are in a position to take one, please let me know and I'll tell you what I need!

These decks were made so one could use a Beogram with  other makes of Hi-Fi. I remember my younger brother using an 1800 with a Technics system.
