If you are into the repair/restoration of vintage TVs, I have three great, old resources for diagnosing and repairing them.
-1957, "Pinpoint TV Troubles in 10 Minutes", over 300 well indexed pages used to teach professionals.
-1969, "The Practical Handbook of TV Repairs", approx. 130 pages.
-1959, "TV Trouble Tracer", symptom/remedy identification wheel.
