I have a schematic showing a part identified as J412, which is probably a National Semiconductor NJFET. The schematic only shows the pin numbers, not the JFET symbol itself, so I can't guess the pinout. I suspect there might at one time have been a generic 8-pin DIP pinout for JFETs, but I can't confirm this. Or I could be wrong about what a J412 is. Of all things, it's part of an ancient solid state guitar amp.
