Thorens 125 MkII: MM or MC cartridge? What's diff?


I purchased a used Thorens 125 MkII. I'm pretty sure the cartridge is a Shure V15VMR. I'm pretty inexperienced with turntables, so I'd like to know whether the cartridge is MM or MC, since the Denon 3802 A/V reciever I'll probably buy will only accept MM. Since I'm so inexperienced, I don't know the difference between MM and MC, let alone what they stand for. Also, is the Thorens only compatable with one of these cartridges, regardless of whether it's a Shure?
Thanks,
Steve

Mobil One (or an equivalent synthetic) is a great bearing Oil. One of the lighter viscosities is the ticket. It's also good in your car engine....
It's great to find someone who seems to know anything about the Thorens TD 125, so I'll take my chance and ask my question. I own a Thorens TD 125, original version, with SME 3009 arm and a rather new Ortofon MC 15 Super cartridge. I had the deck rewired with Van den Hul Cable. My question concerns the SME-arm, which has rather loose bearings. What arm would be the best to replace it with? Since I'm a little short on money please don't tell me only a SME series V would do.... I would like to keep my Ortofon cartridge.....
