Hi, I'm new to this. I'm building Moog oscillators, and haven't been able to find some of these parts. Can someone please tell me what the cross-references are for the following: Transistors- 2N3804, 2N3954, E112 (unijunction), E400 Diode- A141A Ic- 796 If any of these still exist, where can I get them? Thanks, Tom
