    Anybody know replacements for 2SC3329 and 2SC1246?

    Please help me understand what would be good replacements for 2sc3329 and 2sc1246 transistors in my phono preamp section in a NAD 7140. They seem to be making lots of white noise, even with no input. Also seem to be hard to find! Thank you!
