I am selling a pair of Sylvania 6SN7GT Bad Boy three-rivet, manufactured in 1951, last week of the year. Black T-shaped plates, bottom foil getter, copper grid posts. Flashing is full and bright.
These are from a modest tube collection acquired since the early 1990s. I contracted testing of these to tube dealer TC Tubes in MN, who use an Amplitrex AT-1000. The pair test as NOS and are excellent in every way, including very low noise.
Pair 1 GM/transconductance:
Tube 1 - 100% @ 2600/100% @ 2600 | Tube 2 - 100% @ 2600/100% @ 2600
If you're looking for these, it doesn't get better; guaranteed as advertised or return. $7 shipping CONUS, actual shipping otherwise. Thank you for looking!
