This item was leftover parts from my family’s radio repair shop that closed 4 decades ago. We fixed mostly televisions and stereos but my Grandfather first opened the shop in the 1940’s and fixed radios of all kinds. My Father kept the really old parts and tubes that belonged to my Grandfather in boxes and parts bins for years. I have been recently going through it all and I am selling most of the parts other than the ones I might use personally.
