Matched quad of Holland Amperex 6DJ8's date code Delta3K2 from 1963 with Halo getters. Recent purchase from Ebay, not noisy or microphonic, I simply prefer the sound of other tubes (also Amperex 6DJ8, but different structure from 1969) in my preamp.
Ebay seller noted that all 4 tubes tested 120/120 on a TV-7D.
Asking $80 + USPS shipping from 90024.
