Jc2000 said it all -- i.e., no problem there. Just to add that IMO, you could consider investing in upgrading the LP12 &/or arm to latest specs (if it isn't already), and keep the Troika (retipping, depending on wear). The Troika is, indeed, one of the best sounding cartridges for the traditional LP12 configuration and easy to set up, too: I expect it'll keep you happy -- it's a very musical TT combo!
