Like new, break in hours only, considered the holy grail of 6922 tubes. These are in mint condition with the original boxes. Platinum grade from Upscale Audio (https://www.upscaleaudio.com/collec...cts/telefunken-e88cc-6922?variant=21828935365). I bought these for my Schiit MJ2 but sold that system soon after getting the tubes.
