If you're buying them at Pep Boys for 50 cents each as "3/4 inch
O-rings", a typical automotive part, it's not a bad investment.

As opposed to the machined tungsten caps with tie-down springs I've
seen for $60/pair?
There may be some truth to it. After all, they do often glue down
electrolytic caps of size. But do dampers really help or exacerbate
the problem? They are confining the glass from moving but what does
this do to the filament, grid, etc?
