I've been looking around for a while to buy on of these sweet low noise JFET pairs from Linear Systems, but it seems like they are not available from large component suppliers (digikey, mouser, farnell etc.). Are they even in production? I live in Turkey, so ebay and small suppliers are not an option because of high shipping. I need 10-20 of these for now, but I am going to need them in large quantities in a long run (a few thousands). Is there a reliable supplier of these JFETs that has somewhat reasonable shipping option?
I am waiting for your suggestions.
