I just thought of another help if you are starting out on repairing these old radios. Right here in the Library section of the main site you will find this... Everybody’s Radio Manual: How to Build and Repair Radio Receivers  . It is good reading. I have a hard copy in my own library. It will teach you a lot about the basics. It is an old book, from the period when these radios were built, so it is well suited to the receivers we work on.
