Tube on the right reminds me of Darth Vader....

Or a tiny robo-warrior wearing a helmet :-)

When I bought mine, the idiot seller mispacked it and the two other tubes in
back were destroyed. It cost a small fortune to find replacements in Europe.
On my set, the metallic shielding on the rightmost tube is colored gold, not
silver.

Incidentally, that stacked-looking thingie next to the OP's silver Darth
tube should not be floating around loose at the end of very thin red wires.
No idea what's going on there, but it sure doesn't look "factory."
