Welcome to the Phorum!
Schematic for the chassis: https://philcoradio.com/library/download...8-1949.pdf
Fortunately your set does not have the FM1000 tube which is very hard to find these days. Tubes are often still good but should be checked with a tube tester. There is at least one vintage radio club in your area that you can surely find some local help as well. See: https://cc-awa.club/
Info on phonograph if it is still the original M-9: https://philcoradio.com/library/download...8-1949.pdf
or possibly https://philcoradio.com/library/download...8-1949.pdf
Repair of the electronics will take some work assuming it has not been restored recently. I would start with the radio chassis since that needs to work to be able to hear the phonograph. All the paper and electrolytic capacitors need to be replaced. Usually any mica caps are still good. Check and replace any out of spec resistors and as Mike, said check for crumbling wire insulation. You'll need at a minimum a soldering iron and a multimeter. Once the set is working an alignment of the set can improve things and will require a signal generator to adjust things. Our resources pages are helpful for finding components: https://philcoradio.com/library/index.ph...tegorized/
Take some time to read through some restorations in the Phorum threads to get an understanding of some of the techniques used. There are Service tips available in our Library at https://philcoradio.com/library/index.php/shop-talk/ be sure to scroll past the "Rons Radios" section as there is a "Techniques" section below it. Take your time, take lots of photographs as you go to help put things back together correctly. Its best to replace one item at a time although in some situations that is difficult to do because components are often close together.
