In the past decade, TJ Full Music 300B tubes has earned solid reputation in the international hi-fi market and has been reviewed by many major hi-fi magazines such as etc..Since last year, TJ Full Music has expanded to 2nd manufacturer facility in Tianjin City, China to manufacture high end gold pin, box plate 12AX7 and 12AU7 tubes. Audiophiles who have tried the 12AX7 and 12AU7 commented that they are even superior to the Telefunken ECC83 tube.

Grant Fidelity currently carries 3 models of TJ Fullmusic 300B tubes. They include:
- 300B/n: Premium Mesh Plate
- 300B/C: Carbon Plate
- 300B/SE: Special Edition Carbon Plate

The 300B/n Premium mesh plate 300B tubes are one of TJ Fullmusic's top sellers. They are the most beautiful looking 300B tubes when lighten up and sound exceptionally musical. The mesh plate version is known for its air, openness and smoothness.

TJ Fullmusic has confirmed to us that the dome shape or globe shape tube has exactly the same chacteristics and theorically there is no sonic difference. All our current in-stock tubes are of globe shape.

The print color of the model number on the tube base DOES NOT indicate quality difference - just different production date.

We offer standard 30 days warranty included in listing price, and optional 12 months warranty for $40 per pair directly from Calgary, Canada.
