[Boatanchors] National HFS help

[k0ewu at juno.com]

HI ALL.I acquired the HFS rx as the coil set was complete, I knew that 
a transformer was missing bt did not think too much about it..
Now I find that someone had added a 6T8 multiple diode thing,
 removed all of the components around the 6J5 detector as well
 as the audio tx.
 Was there a mod to convert this rx to fm at one time?
What I need is the audio tx and the values of the two rf chokes 
in the detector circuit. I have some National knobs and a MCN dial 
or other parts to trade.  Orgreen stuff..
