Evening Vinyl Lovers! Had a heck of a stash given to me today by the Father-in-law. What a guy! Included in it: Original pressings of Floyd and a good deal of Beatles! The less I say about the wife's old NKOTB & Bros the better! My question is this: Do I need a Mono cartridge for them? And if so, can you recommend one for a Rega P3 2016? Many thanks!
