Valvo ECC88's? What, where, more?

71.202.2.98

Greetings. I’ve tried several kinds of 6922’s in my CJ 17LSII preamp, and the ones that sound the best by far are labeled Valvo ECC88. The back side of the tube has the following information:

104 2160 C2 (around the side of the tube)
Made In
Germany
V.E.B
Funkwerk

I cannot recall where or when I bought them. The white boxes say they are Amperex 6922 1970 NOS, hand written. What are they and how do I get some more? I need four for the CJ. Thanks.
