On sale is one matching pair of Sylvania JAN CHS 6SN7GT . Tubes were made with special 3 holes plates and copper posts in the early 50's. One tube dated 135 and the other tube 147. These tubes become rare and rare. They have been tested by my TV-2C/U military grade tube tester, the readings were 92/95 and 97/91 out of 100/100, also sound tested by a 300B SE Amplifier, the sound stage was very wide and deep, extremely low noise, clean, dynamics and extended on both ends with details. These are the right tubes especially for your Head Phone Amp or Pre-Amp.
