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?
