Hi,
Here's a photo of my problem in troubleshooting a Philco 90:

The Rider's sheet mentions cryptic abbreviations for coil pins (I believe) but I haven't decoded them. Can anyone help? The 90 I have is apparently the latest model chassis and works with 24As in the front end but not with 35s. Also, the RF section is not working so I'm assuming it's in the Antenna input coil. It looks good (no apparent corrosion, and I haven't removed it) but all resistance readings are infinity.
