Genalex Gold Lion KT-88.  2 Matched Quads available.  These were in my Ayon Audio Triton.  They have about 150 hours max.  I upgraded to the $1200 Black Bottle Treasures and no longer need these.  Looking for $150 plus shipping per quad ($300 new).  See user name "mikeg" feedback on a-gon.

I don't know where you buy your tubes but a matched quad of GL KT-88 can can be bought new for $200.00 at most places.Just a thought.
