Tungsrams are nice. NOS Teslas are also nice, but seem to have gotten expensive. I think white label Amperex, either Herleen Holland or USA, are the best option. I have at least 60 of them. :~)
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
