1935 Philco 60B, Version 6, Run #11, IF Coil Open
#1

   
I started the restoration of this radio a couple days ago. And after spending a while researching exactly what version I had (Many thanks to the Website Library!) I checked all the coils for continuity and discovered the lower section of the Primary on the Antenna coil is open and the Primary on the 2nd IF.
I have the Antenna Coil prepared to wind, just waiting for the proper gauge wire to arrive from Remington. This should be an easy fix, and also confirmation in the Library on the details on this coil.
The IF Coil may be more of a problem. It is the Primary winding on the 2nd IF transformer. The coil at the bottom in the picture. It is Item #25 on the Parts List in the Library for this Version (Run) of the 60B. Part #32-1050. It has stamped on the top center an "A7", if that has any significance, along with a "L1" on the Ground Bracket and some yellow paint on the Top (Wire side) of the unit.
I haven't seen any information on the wire size or number of turns for this, and also not sure my winding expertise is up to the task for this one! Are suitable replacements available for these? The Compensating Condensers are mounted separately. The 1st IF does have a different Part Number (32-1049) and is obviously different based on the coil resistance shown on the schematic.
I'm a bit hesitant to try to locate the same part, as it is widely known these have a high rate of failure.
SO I'm looking to the experts to provide some guidance on how to remedy the open coil, or obtain a suitable replacement.
Otherwise this should be a fairly straightforward Restore - Replace all the Block caps, Electrolytics, verify the Mica Caps and resistors, expecting many of the resistors to be out-of-spec. Some new washers under the tuning cap and a replacement tuning dial from RadioDaze.
Thanks in advance for any information!

Thanks
