2 thoughts on “RCA Victor 12au7/ECC82 Black Plates D-getter 1949

  1. Wanted to share my latest find – RCA Victor, before they became just Victor. The tubes has been manufactured in 1949! The earliest production of 12au7 was in 1946, but out of 9,000-10,000 12au7 tubes that I sorted through, 1946 never came up.

    Sound wise, this tube is a great example of sound from 1940s and early 1950. Very transparent, but rich at the same time. Something has changed at the end of 1950s and a lot of tubes lost their transparency – they remained rich, but lost their liveliness.
