WISA Audio Pump for ET2 tonearm

Wow, this is pretty incredible. I had one of those break mid LP just three weeks ago! The racket of the pump housing vibrating against the mounting plate was something! After I determined the source of the racket, another one broke. I turned it upside down and placed it on a stack of soft fabric for the time being. If I find replacements, I will let you know. You may want to ask this question in the ET2 tonearm thread. Someone there might know where to get replacements.

I found replacements at my work years ago. I believe they were bumper/stops for metal door/frames?

I always look at things when I'm out at hardware stores, and try to reimagine other uses for them. You could just put a mouse pad underneath it or the stick on clear vinyl dots?

If the OP's pump is like mine, the rubber pieces are o-rings.  It's just a matter of finding the right size.  I have a pretty good local o-rings source, so I will see what I can find.  This is what the bottom of mine looks like.
