Several years ago I bought a Pioneer PL-88F for $60 -- all it needed was a new cartridge ... New cartridge acquired $95 --- Not working quite right ... Sent in for repairs --- They say it's a cracked needle and I need a new one ... Radio Shack (where I got the first cartridge) says it's not available -- Pioneer says it is and I can order it online (yeah right! without a Visa to pay for it) ... Local phono repair shop says they have Moving Magnet and they'll put it in --- PL-88F cartridge (PN41MC) is Moving Coil ... Will it fit? Will it sound right? What's the difference?
