TJ Full Music 300B/SE Special Edition Premium - MSRP $700.00/pair + $50 optional extended warranty

Although this is a wonderful tube, we have no choice but to discontinue it due to the exceptionally high shipping damage ratio. It is not financially feasible for us to continue carry this product anymore. Thanks for previous customers' patronage and we hope you will find an alternative 300B tube from our current product line.

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 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 Full Music 300B tubes. They include: - 300B/n: Premium Mesh Plate - 300B/C: Carbon Plate - 300B/SE: Special Edition Carbon Plate The 300B/SE is a special edition of the 300B/C carbon plate tubes. By the looks, they are nearly identical. Although the factory will not disclose the details of the technical difference of the 300B/SE version to the 300B/C version, they do comment that higher grade components are used for the SE version and manufacturing process is quite different too. As to the sound of the SE version, TJ Fullmusic set their direct competition as the legendary Western Electric.

As far as we know through TJ Fullmusic, Grant Fidelity is the first and so far only authorized distributor who carries the 300B/SE version in North America. 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. Latest TJ tubes mostly come in red printed model number on the base. 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 and optional 12 months warranty for extra $50 per pair directly from Calgary, Canada.

"...Possibily I prefer the TJ-SE to the Western Electric in part because of its resemblance to the 211 in its ability to clarify texture, catch and release attacks, and maintain order in the harmonic structure, which is absolutely necessary to both accurately reproduce timbres and propel the bass line, without which the melody has nothing to hang onto."
