Philco Model 90 Speakers
#7

Steve,
I figured I had little to lose so I did some surgery on the field coil and was lucky enough to find the discontinuity right where the lead-in wire connects to the fine coil wire. Soldered it back together and used a drop or two of Super Glue to hold things in place. Took about 30 minuites from the time I discovered the field coil was open until I made the repair, put things back together, and made some tests. The DC resistance is 3200 ohms; within 20% of what you said it should be. Thanks for your help.

Lou
