Would a "good enough" substitute for an IF transformer consist of a
couple of commercially manufactured inductances or chokes of the "right"
inductance value, each in parallel with capacitance to provide resonance
at the intermediate frequency and joined at the top by a small amount of
capacitance? In other words a pi network with each leg a resonant
parallel combination of L and C and the top a coupling capacitor? Do we
really need mutual inductance between the anode of one stage and the
grid of the succeeding stage?
