Hello folks - I just discovered a brand new MM5 in my loft (clearly belonged to my late father) and opened it up - still in its original packaging and used in on my 3300 turntable but the distortion was terrible. Ended up transferring it to a 5500 turntable with the same effect. Surely, this cartridge could not be damaged or tip ruined as it was brand new and never used. Any possible suggestions? Thank you
