If'n I should have to replace the existing one what style will fit? And also, how does one safely remove the head shell from the tonearm.[/QUOTE
From my DUAL owners manual...
"This turntable will accept any cartridge weighing from 5.5 to 10g(including mounting hardware) and having standard 1/2" spaced mounting holes."
"To mount the cartridge, detach the cartridge holder from the tonearm by moving the tonearm lift back, while holding the cartridge holder with your hand to prevent its falling down when the lock is released."
Nice TT!
