Leroy will present at the next PAARA general meeting in Menlo Park on January 8th. His presentation will be an overview of tube technology and tube testing from his perspective as Supervisor at CPI, formerly known as Eimac in San Carlos. Now based in Palo Alto, CPI supplies a wide range of vacuum tubes to the broadcast, military and ham radio industries for all kinds of RF applications. From milliwatts to kilowatts, Leroy is responsible for maintaining the test labs responsible for validating the tube quality during the manufacturing and repair processes.
