For sale on Ebay now... a cool matched pair... and nice pixes, as well...
... as I use 4 of these on my Mayer LCR Phono stage and also if I Chip'n'Dale-ed 4 x 4 quartets (16) as spares in the last years, all with original white/blue Western Electric original carton box... nonetheless, every time I find these elusive and expensive, BUT most of, INCREDIBLY nicely, smooth and natural sounding tubes, my (audio) heart beats.
