Baldwin organ used Raytheon 12AU7 black plate in the era of 1957 to 1961 & some early 1962 organs, never RCA manufacture. During 1962, the Raytheon label tubes were out sourced to Japan with grey plates. Raytheon used yellow writing as well. I never seen a RCA 12AU7 with yellow writing.
Hope this helps.
