This vintage lot includes five large electron tubes from various brands, including Silvania, RCA, GE, and Raytheon. These tubes are classified as electron tubes and are suitable for use in radios and TVs from the vintage era. While the condition of these tubes is not specified, they are being sold as untested and probably used, making them perfect for collectors or hobbyists looking for unique vintage items. The lot consists of a mix of brands and types, providing a diverse selection of electron tubes for enthusiasts.  Item specifics say used. I am unable to test. I do believe  they were in working order when store because they were carefully  wrapped  and stored in boxes. I  assume the technician felt that they were still functioning.  That being said, I can not guarantee functionality. Please look them over good and ask any questions you may have.
