Where to buy quality phono connectors for chassis

You can get gold plated from Radio Shack. At a reasonable price too.

Lewm: Have you ever done a dstructive test to see what the material is? Most likely it could be brass, tinned brass.

I don't have any extras to wreck, but if I find one I'll post what I find. Gold is good enough for so many things, and the primary concern is corrosion resistance. The thickness on all connectors is quite thin, but it is effective. Also, what structural metal do you consider "best?" I know silver is the best, but not everything is made with silver. SMT components with silver connectors? I doubt it. Radial or axial leads on resistors & capacitors, I doubt it. So, take one part in the electronic chain made out of a silver wire & all the others out of copper or brass alloy kind of negates the benefit of the silver doesn't it? Just asking...
