Essentially, a brand new tube with less than twenty hours on it, probably closer to ten. It is branded Phillips, but was made by Mullard.
I bought it for my Line Magnetic 508ia, and it was indeed as magical in that amp as everyone says. A change in speakers resulted in a change in amps, so grab a great deal on an incredible tube.
I purchased this tube from Tube Depot this summer for $250. Will sell for $195 shipped. Buy a practically new tube and save $50 plus shipping.
