It is common practice, when using single coils in a staggered arrangement, to place them in the plate circuit while the following grid circuit uses a coupling ... The form of an IF system does not change with a moderate change in intermediate frequency. The circuit in Fig. 9 is designed for the 40- mc range, but, with suitable tuned circuits, it could be made to work satisfactorily in the 20- mc range. ... The system contains four IF stages and bifilar coils are employed between all of them.
