Ahhh, I see... If the cartridge is subjected to
excessive shock, the
disk pops loose from the magnetic holder in the bottom, and rattles
around. I wish I remember which ones made 'clunking' sounds as I
unboxed them.
Thanks for all the answers!
Almost but not quite. the hub is a very sturdy bolted up
structure as it has to hod on to a 14" disk spiining at high
speed.
However, The disk is 14" and only 1/8" thick aluminum so a
shock in the wrong direction can warp it just like an only vinyl
record in the sun.
