Radio Corporation of America


No introduction needed. Formed in 1919, the giant of the radio tube world has perhaps the most number of variants of all manufacturers. My focus will be to add something new to the puzzle of figuring out these high quality tubes.

One of several manufacturers 'contracted' to make tubes for RCA branding.

Some of the same companies made tubes for other brands: notably Cunningham / Audiotron Sales Co.
