The first question to ask is can you solder?The second question to ask is do you know how to use a volt-ohm meter? If you can do both of those things then you could probably restore your radio. One thing to keep in mind, early 40s Philco sets, particularly U.S made ones, used a lot of rubber covered wire that has often gone rock had and will crumble if disturbed. It's not too hard to deal with in most cases but it often goes up into the IF cans and other coils so if you have bad eyesight or aren't used to fine soldering work you had better practice first or farm out the restoration job.
