  Thanks, but those are plated brass.. Looking for silver

    I see that you want to make a perfect replica of the Audio Note Ongaku, down to the turrets.
    
    Last time I checked 99% of the resistors and capacitors have tinned copper leads. You want those parts to connect well with each other...and IMHO a silver turret is not the shortest path.
    
    A turret is just a turret, a support, it allows one to get a firm contact between parts leads. You want the electricity to flow directly from part to part, not from a cap lead to a turret and then another solder joint to a resistor lead.
    
    A few japanese DIYers make amps by cleaning/scraping the parts leads and twisting them together firmly (no turrets, 3-dimensional layout).
    If the amp powers up and works perfectly with no solder, then they solder everything. (quoted from L'Audiophile, Jean Hiraga, circa 1987).
    I do not recommend this approach for safety reasons, however the key to a good electrical connection is a good, clean and TIGHT mechanical joint before soldering. Using silver turrets will not make copper-leaded parts sound any better.
    
    Have fun :)

      almost....

      I mentioned that I wanted to use these in a PCB. I will have no components soldered directly to the turret. The turret will be used for wirinig to be connected to the PCB. I make my own PCB's that I silver plate the traces. A solid silver turret, between a silver wire and a silver plated PCB is what I'm after. I'd like to avoid tin and brass in the interface (besides the trace tin in the silver solder).

        I respect perfectionism, it leads to great accomplishments.
        What about these:

      Wow, I will have to look into that sometime. I have been a little surprised that AN kits don't do the lead over lead on turrets so much. I have built 2 amps that have no terminal strips, and a preamp that had one in the power supply, but it got toasted in shipping.
