Those Telefunkens are not from the same year, assuming the pix are of the actual tuebs. Not sure if that matters to you, but the date codes suggest 1968 and 1971. Doesn't mean they won't work together. Just sayin'.
Here's a quick tutorial on dating Telefunkens, using a real code as an example:
12140040
U is the Ulm plant where it was made
reverse the first two numbers for the date which would be 21
the 3rd and 5th number is the month which is October
the 4th digit is the last number of the year which is 1974
That means the tube was made Oct 21,1974 in the Ulm plant
and one other crucial bit of info:
"Tubes after 1968 started with a letter indicating the plant and seven numbers that followed.Since we were past the year 1964 which has a 4 in the number,the only logical conclusion would be 1974."

mercedesman (
TubeHunter) on eBay usually has a lot of Amperex pairs. As I noted above, I'm digging my 1967 Orange Globes with the HE-500s. mercedesman recommended the Bugle Boy Straightman, and I'm glad he did. I got a 1961 pair, and they're awesome. I'd rate them above the OGs. He definitely had a few Straight Man pairs a week or so ago.
