Philco 95 - 1st RF Transformer issues
#13
Question 

I've got this old Philco 95 that I am restoring!

Now that I have actually gotten around to it...there are a few more problems here than I had originally thought Icon_eek

Any idea what has been done to the rf transformers? Specifically, it's the first two that I am on now...
   

They have been attached to the top of the cans, instead of at the bottom (like the other two).

As well, the first appears to have had its secondary completely removed:
   

In that first pic you can see the bulk of the modifications that were done to it. My knowledge of old AM radios isn't the greatest...but from what I can see, it appears as if the first RF transformer has been turned into an inductor tied to one end of the first compensating condenser (along with the antenna connection) and ground. The cathode connection of the first RF tube has been disconnected.

Any idea what whoever worked on this last is trying to do?  Icon_confused
