[sdiy] source for brass or other exotic banana jacks (non-nickel)

[Anthony Bisset]

Hey All

I'm in the process of planing some spalted maple for the surface of a
modular interface and plastic banana jacks are compromising the look.
I've found plenty of nickel plated banana jacks across the interweb but
brass or boron would look a lot better.  The little bit of JCD that I
have uses round brass Jacks, these would be ideal, but I have no idea
where to get them...

I'm interested in vintage/unusual plastic jacks as well, so If anyone can
help me out or point to sources that'd be great!
Cheers,

Anthony
