I purchased them from a TV repair store, which had most all tubes for anything, and the time was 1965-1967, I guess one can be sure, unless there were same time travel tubes, must were made when, or before I purchased them. They were purchased in France.
As far as I know, the RTC tubes I purchased 1964-1967, were all before 1968, I sure Most were used, like Mazda, in broadcasting, and some for industrial products and a few radio enthusiasts.
Most for audio were the 12AX7, 12AT7, 12AU7, 12AU7S were used by musicians, 12AX7 was used in some audio, but really,more the one with higher mu. I do not remember any of the 6922 being used in preamp that much and why I have them is somewhat coincidence?
I first began using them when some older amps needed new tubes, and later, with ARC, I changed out all those Russian tubes they use with Siemans, Mullard and some Philips/ Amperex none purchased after 1970.
