Yes jcassity, that was in reply to your 'current status check'. Other than the current draw through R127 in FM, and the low end FM stations showing up at the high end, I am happy with the way it works.
I have taken voltage readings at each tube pin and compared to those listed in Sams, but those readings are in AM mode. I have taken all the same readings in FM but don't know if they are valid or not, since I don't have reference voltages for FM. The Philco schematic does show voltages at various points in the circuit for both AM and FM, but not for each tube pin.
