Got this from a friend on head-fi a little while ago for my Ampsandsound Forge. Hailed as a "holy grain" of 6SL7 tubes, it sounds excellent, buttery smooth and quite full/lush. But on my amp it does have a very slight hum, hence the very low price.

Only used it for around 5 hours myself, and when I got it the triodes measured 55/48 (min of 32 to be considered "good"). So not quite NOS, but still with a lot of life left. These tubes were built to last.

Here's a link to the previous ad for better pictures: https://www.head-fi.org/classifieds/rca-red-base-5691-tube-6sl7-replacement.29065/

I'll take care of shipping in CONUS and PP fees. PM with any questions.

Open to offers!

Hello,

Are the tubes still for sale? I’m looking for these or similar 6SL7. I’m looking for a pair.

Best, Mark
Sorry, I included this tube with my amp that I sold a while ago. They're such great, warm tubes though! Good luck with your search.
