You can increase the tonearm's mass by packing the headshell with 3M
StripCalk (a non-hardening putty sold in hardware stores for window
caulking and in auto-supply stores for panel dampening). Obviously
you'll have to rebalance the arm after packing the headshell. The
Stripcalk also can help deaden vibrations of the headshell and cartridge
body. Mortite window caulk will also work, but it dries out and hardens,
plus cats love to play with it.
