Seeking suggestions for 6922 tubes

Some years ago Kevin Deal had a good price on a stash of Telefunken gold pin 6922 tubes. At the time I needed a pair for my DAC, and they worked out very well. I'm still using them today. Now I find myself with a preamp that also uses a pair, and it seems the Telefunkens are not available at this time. 

I would appreciate suggestions of alternate brands that I might use for this purpose.

Thanks, John
