This Manual does cover a lot of ground and These Schematics show how to troubleshoot all the tubes and how to bring A non-working unit back to life, even if you can not read these schematics or Diagrams they are invaluable to a Service Technician working on a Older Unit. Plate Voltages are shown, Capacitor and resistor Values are show if one is Burned up or missing. All Tube Numbers are shown if a tube is missing. Speaker Field resistance values are shown to aid in troubleshooting the Speaker and Sound output. This is a High Quality, Easy to read re-production from Original Schematics. (Note: Picture shown is only an Example) ALSO: If you are looking for Old Radio Schematics, ALL Makes, All Models (US Only) I am always listing new Sets, Good Luck. Key , Manual CD (Remember this is a CD, You must be satisfied with its operation, no complaints yet. Copyright Reserved and CD Coded for Tracing . This is a CD and comes w/ Adobe Reader. Great CD with Thumbnails and easy to Print from. Good Luck
