1924 would be the year of the 'peanut' tube. Anything that would let Flivers tune in from their portable sets. Even the storage battery folks were getting in on the action, buying adapters that let anyone use dry cell tubes.


By the time the UV-199 made it into production, RCA was leveraging manufacturing by Westinghouse Lamp Co. as well as GE's Harrison and Cleveland plants. 

Customers had been left waiting, and the final arrival of the first tubes had sellers listing the Cunningham and Radiotron brandings side by side.
