Up for sale are some single tubes from my collection. All have been tested with calibrated Weston 981 for transconductance. In addition, the tubes have also been tested for noise in working amps. These are guaranteed excellent, working, and noise-free tubes. Prices include shipping to CONUS. PM me is interested.
