I still have a couple left.
These have all been tested on a B&K500 transconductance tester which has been recently calibrated. All tubes test very strong, with a new 6sn7 testing at 5200gm. Also, no gas or shorts.
3-RCA 6sn7gt grey glass 5000gm,5000gm, and 5300gm 40$ each.
3-Sylvania 6sn7gt - 5400gm & 5100gm & 5900gm 30$ each.
1950 & 1951 & 1952 date codes (not bad boys)
2-Sylvania 6sn7wgt - 5425gm & 5800gm 140$ pair.
Brown base short bottles.
