"Hi-End, Not High Priced" ...... Best Value Chinese Hi-Fi

Discontinued and out of stock.

TJ Full Music was established in 1990s by one of the pioneers of Chinese vacuum tube industry. To date, the company is still run by the founder, who is in his 70s and his son who is actively involved in day-to-day sales and marketing. 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 EnjoyTheMusic.com 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/C Carbon plate 300B tubes offers more details and dynamics than the mesh plate. It is more durable because the plate runs at a slightly lower current than the mesh plate tube. Such a feature will further stretch your investment in these high quality tubes.

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.

All TJ Fullmusic 300B tubes distributed by Grant Fidelity comes in factory matched pairs, with white ceramic base and gold pin, at no extra charges to customers.

We offer standard 30 days warranty included in listing price.
