Bingo! You nailed it Terry. Open primary on the 2nd IF transformer. I removed the can and checked it again, it's definitely an open coil, not a shorted wire. That's a first for me, an open IF transfomer. Wonder what caused the failure.
So...this has me digging through my parts boxes. I parted out a 1941 Philco console chassis with a similar tube count years back and I THINK I found a suitable IF can that I can use. It has the 51K resistor inside, and the two small value capacitors. The primary and secondary ohm values are a bit off, but not drastically. At this point, I have nothing to lose trying it. The original would need to be rewound and I have never tackled rewinding an IF transformer before. Rewinding the ANT and OSC coils were bad enough on the model 89 and 84's I've worked on!![Icon_lol Icon_lol](https://philcoradio.com/phorum/images/smilies/icon_lol.gif)
Will tackle installing it tomorrow night after the daily work grind. Stay tuned...I hope I will be able to with this IF can!
