Philco 49-607 inop
#13

Did the 1U5 test out at Zero? If so, the filament is open. The filaments of the various tubes except the rectifier are in series. This does not explain why the 117Z3 does not glow when in the radio; its filament across the power line after the switches. This is why I think that you have a switch issue. The 430 Ohm value for the filament of the 117Z3 is believable. Recheck the AC / Battery Switch, particularly for continuity between 3 and 6, 11 and 7, and recheck the power switch.
