Clear schematic and notes from forum moderator (not free, not me, but very much worth it)

Fuzzy schematic and notes (free, and good enough to get started)

Basically you should replace all the "fixed condensers" which translates into paper capacitors which cannot be reliably tested once they are as old as this. I find it easy to replace the small carbon resistors at the same time, as they have invariably drifted up in value, and cost only pennies. This will make a huge difference in performance and longevity of the set. surprisingly the most dependable components in these old timers, with a few exceptions, are the tubes.
You can get through this and will have a fine set in the end. Take your time and ask plenty of questions.
Lots of sources for parts, Just Radios, Jameco, Mouser, Digikey, many more. Mostly you should make an exhaustive list of everything you want, including a few spares of common value components, solder, deoxit, tools, etc... so you don't get ripped off on shipping.
Let us know how it goes.
