History - these came with my Allnic A6000 Monblock Amplifiers, purchased late 2012. They were never used. I stored them as extras and used Emission Labs 300b XLS for more amperage. They have been in my climate controlled wine cellar all this time. Seen pictured are 2 matched pairs and 2 singles. I had loaned out two tubes as extras for Waversa Systems presentation at CES in January. Those two are on return and were never used. Just back up in case. Both Waversa and Allnic in this amp do not require match pairs. So I have 2 match pairs now and maybe 2 more match pairs next week.
My buyer wanted to negotiate a better price and opted not to buy these tubes as extras.
$50 each. Retail new for $150 plus. They are a decent tube and for this price may be of interest here.
