I have for sale two platinum rated, matched tubes from Upscale Audio (lowest noise/microphony available, tightest triode balance).
The Tungsram 6922s are super quiet and very clean sounding, they aren't necessarily warm tubes, but are warmer than a solid state O2 or something like that. Very detailed in all areas, a pleasure to listen to. I really like these tubes, but I recently got some other tubes and don't need these anymore. These have been used less than 100 hours in my Lyr 2. I've only had them for a month. Keep in mind 6922s typically last around 10,000 hours, so 100 hours is 1% of their life... These tubes are $80 each new, so I'm asking $110 shipped to CONUS (buyer pays PayPal, which is $3.59) since they're really lightly used. That's 1% used for 70% the price. I'll ship to other places for additional cost at my discretion.
They come in the original NOS boxes. The tubes are from the late 1960s/early 1970s. The tube labels are different colors, but Upscale matches based on measurement, not the label, which is how it should be if you care about actual audio quality.
