Tube ID & Code Help Needed
I aquired an old 60's Lowery organ over the weekend.
Long story short, I got a quad of 7591's out of it, But I have never seen this particular brand. The date codes on the 12AX7's are RCA style year/week (65-17) But The 7591's use a code I am not familar with, Possible Sylvania? I would Like to date these. See pictures I have never heard of CMI tubes , perhaps re-labels. They say made it usa. CMI 7591 CMI 7591 Top View Thanks Trout |
