Shuguang Black Treasure Series KT88 Octet set

*Matched octet(8) Shuguang Black Treasure Series KT88-Z "Premium Grade" tubes in luxury factory boxes - 2 per box, 4 boxes total. New in boxes only opened to check shipping condition. I bought these to run in my tubes amps that never came. I would prefer to sell these as an octet but will consider splitting into quads if I can get 2 buyers interested. No low ball offers please, I'm looking to recoup most of my cash back not take a bath so if you've ever been interested in these tubes here is your chance. Google for reviews! Buy with confidence, my feedback speaks for itself. Thank you, Dean *All matched octet: Ia = 52 mA for each tube, - factory measurement cards included. FWIW, I waited almost a month for a matched octet to become available - be a shame to break up the set.
