Welcome to the Phorum!
First things first.
Don't power it on again until you have at least replaced the electrolytic capacitors C101 and C102. Eventually all the paper capacitors should be replaced and any of the resistors that are more than 20% off their spec value as well.
If you are new to working on vintage electronics like this and you want to do the restoration/repair yourself you will need to do a lot of reading to learn about the restoration process. Read through some of the restorations that folks have done on this site in older threads. We have service tips and information in our Library as well. That is at: https://philcoradio.com/library/
A good beginners read is from Phil Nelson's site: https://www.antiqueradio.org/begin.htm If you want someone else to work on it there are folks who do that. A 46-1209 schematic is found at: https://philcoradio.com/library/download...6-1947.pdf
You will need a digital volt/ohm meter and a soldering iron at a minimum and a signal generator to properly align the set.
It will not work if there are missing vacuum tubes. Even if the filaments are glowing, the tube may not be working correctly. A tube tester can help diagnose bad tubes. If you decide to restore the set, go slowly, take a LOT of photographs of the wiring and components as you disconnect things and resolder and reconnect. The photos help you put it all back together. There are many folks here on the Phorum far more skilled than I who can help you through this. Ask questions in this thread as you go along and folks will respond. There will even be some folks that have worked on a 46-1209. Adding pictures sometimes also helps.
