Introduction: I can repair most any antique/ historic radios,sound amplifiers,televisions[ depending on parts availability], test equipment of the vacuam tube time and era, electric motors, and some of the first transistor electronic equipment. I have a rather large accumulation of parts; both old and NOS{ New Old Stock].
I have did this now for fifty years since I since I was a kid and I have studied under older engineers and repair people. I also have my own personal library and files that I have created over these years.
