Small vs big Telefunken logo on 12ax7...
I have acquired some used ribbed plate telefunken 12ax7s recently and
noticed there were differences from what I could see on the web: (1)same features - Telefunken logo, clean diamond at base with numbers, "Made in Western-Germany", "ECC83/12AX7", and the prints are water soluble (easy to wipe off). (2)different features - The "Telefunken" logo is small, probably ony 3/4 of the others. The "ECC83/12AX7" label is above the logo, and there is no vertically transposed date code printing on the other side at all, instead there are just 2 small characters saying "w1" (or "wl"). They sound great on my dynaco preamp, a little bit richer in bass compared with the stock dynaco Telefunken oems (subjective of course). Would appreciate info from anyone knows the history/story of these "small" logo teles. Are these old productions? TIA. |
