Two, Sylvania 6SN7GT tubes. Firm bases, excellent silvering. Tubes are matched for dynamic gain and structure- test at 2750-2750 and 2750-2750 where pass/fail is 1625 micromho.
Tubes arrived in excellent condition. Added to the gain (right) side of my Schiit Freya+. Immediate audible improvements in soundstage, imaging, and treble balance over the very good quad NOS Sylvania GTAs I'd been using, although I left the other pair of GTAs on the left side. More holographic with a sweeter treble.
