The larger JW Miller 612-M1 IFs require an additional 50pf SM 
in parallel with the coils (and the existing mica trimmer) to lower 
the frequency from 138Khz to 100Khz. The smaller JW Miller 
1710 IF transformers, which are already 100Khz and are slug 
tuned, have an imbedded capacitor across the coils of roughly
330pf. Did that answer the question ?

What value capacitor did Miller use to resonate the 100 kc IF
transformers?Thanks,

Jeff
