I think there is a different code for the older style tube version verses the octal type. The code 121 is the older and the 122 has the octals. That one has the older tubes in it. No difference in performance as the tubes all have the same mu (gain). I think I only need one more to have all of regen/cathedrals. I don't have the 1935 version with vertical slots under the dial
