I have another question on this radio. Here is a link to the schematics for the 95 late model (http://www.philcoradio.com/tech/images/95.jpg).
The paperwork I have on this set (from Chuck) says that this radio has AVC. To me, it looks like the AVC line starts at item #23 (0.5M resistor), and goes to the secondary of RF transformer #14. The only thing that makes me think that that line is not the AVC is that here the AVC only seems to be affecting the gain of one tube (the third and last 224 RF tube). In other sets, the AVC is usually fed to multiple RF/IF stages (I realize this isn't a superhet, so no IF).
The other option I see is that the AVC is coming off item #26 and feeding to the first two RF stages. I'm really confused by this, which is it? Or is it both?
Thanks in advance,
