Philco 70 Cathedral
#21

Ron Ramirez is right. You don't want that primary wound on top of the secondary. Reason is that the coil is designed for nominal coupling across the band. If you were to wind it on top, you may get better coupling in the lower part of the band, but you would lose total Q in the circuit and also change how it tracks across the band...
