Ty,

Don't know how to decipher the lot numbers. But, the ones which I like have all yellow lettering on the glass. The "T" is in a circle with "wings" drawn on each side.

They are labeled ECC83. Not 12AX7. And are probably 1980's vintage.

Some folks mention different colors (white or orange, I believe) lettering and non-Tungsram logo on the glass.

For whatever it's worth, mine came in the red, white, and blue box. I bought a lot at one time, so I haven't had the need to purchase any recently.

I've put these into several amps. All the owners have liked them. They have good strong mu. And can take abuse. Very strong tone, especially when pushed by a high output guitar in an amp which places hefty voltage (read: old Marshalls & Fenders) onto their gain stage tubes.
