NOS Brown Base GEC 6AS7G tube. I purchased this from fellow head-fi member W0lfd0g last week and used it for approximately 5 hours in my Bottlehead Crack. This tube is guaranteed to be in "like new" condition as the pictures show.
Price is non-negotiable as I am asking for what I paid (which is significantly less than most sell for). Shipping and PayPal fees not included.
