Audio transformer two extra wires ???
#4

I think I was right, this is the audio detector (2nd detector) choke. It probably opened and was replaced by a coild taht was lying there nearby.

Here is the link to my Philco 90 where the recommended value is 2.5mH. They use the same exact choke in both radios with the plate detector.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
