Great score on the Tung Sols. NOS Tungies weren't exactly thick on the ground twenty years ago when I last ran an amp using 6550s. And in this last year when I started looking again for a pair of NOS 6550 there were plenty of GE 6550s of various vintages available but nary a Tung Sol to be seen.I’m most proud of the power tubes: Tung Sol 6550 smooth black plate, one pair, 1st gen, other 3rd gen. I lucked out in purchasing a total of 7 tubes over time from various sources and found 2 matched pairs, with date codes within weeks of each other, from 1958 and 1960. I joke that I don’t listen to any music released after my tubes were manufactured…
