well I have 12B4 preamp, and I the gain is not enough for my card head unit, because car's head unit (cd player) has a 2 Volt output or something.
so I need higher gain,
417a or 5842 is what I'm looking for.ok, where to look for the interstage transformer ? how much and how big ? the problem is I don;t have enough space.
I'm looking fr a very very simple Preamp (little component)
