New Old Stock in original boxes with excellent printing.
They are labeled 6DJ8 / ECC88; Made in Holland in excellent white printing.
They bear the traditional RCA in RCA's red color.
These feature the sound that you buy Holland tubes for, but probably will end up going to a collector because
the boxes and printing on the tubes are both excellent.
Pair A, Tube 1: 12,500 / 12,500; Tube 2: 12,500 / 12,500
Pair B, Tube 1: 12/125 / 12125; Tube 2; 12,125 / 12,125
(Buy both and make a Platinum quad)
$200 for the pair that you have never seen before and probably won't see again in this condition.
