Is anyone using PCL82 tubes?

I am looking for experiences with European brands of this tube. I have some Westinghouse made in England and a few American brands but am having troubles finding a dealer who carries Telefunken, Mullard, Marconi....
You might want to check over at head-fi. There is a small German OTL integrated amp (Eklipse maybe) often used to drive AKG K1000 headphones that uses those tubes. My recollection is that amp was reportedly NOT sensitive to tube rolling.
I'll take a look at head-fi. I have a Vista Audio SET amp that is sensitive to tube rolling. I like Raytheon and RCA so far, but would really like to try more because they are pretty cheap to experiment with.
