There are a few tubes that are recommended time after time in this thread. Some are afailable from sellers in remote countries. How much do we need to worry about fakes? thanks
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

see brent jessee’s page re 6dj8 fake telefunkens with chinese counterfeit silkscreening, informative... bottom line if you know these tubes, key indicators of their construction that identifies them, really convincing fakes won’t get by a cursory look by an experienced tube guy what IS the worry is used tubes, with lots of hours, severe imbalance across the internal dual triodes, and noise/microphonics... let’s face it, these tubes are no longer made for 20-30-40 years now, folks test 'em, use em, pick the good quiet balanced ones and leave em in to make music, set aside the noisy crappy ones, so what remains available today are more of the poor ones that fail on one or more of the above attributes ... unless they are coming out of a reputable seller that tests on all these key parameters or from an old hand who has had gems stashed away for half a lifetime... |
It would seem likely that many USA tube buyers would be locating off-shore sellers through eBay (a common source). Personally: I've never purchased tubes (or- much of anything else) on eBay, from anyone with less than 100% positive feedback. ie: The German tube purveyor I mentioned (audiotubes_de) has maintained that rating, for 23 years and: with over 10,000 transactions. My peace of mind is priceless (to me, anyway)! Happy listening!
