Why are Grant Fidelity Shuguang Treasure tubes the best choice?
1. Double QC process:
All Shuguang Treasure tubes sourced by Grant Fidelity carry not only the Treasure trademark by Shuguang (it's printed on the tubes in Chinese calligraphy), but also has Grant Fidelity label on the base to certify our testing procedure. This double trademarks will endorse that the tubes sold by Grant Fidelity have successfully passed both Shuguang factory QC and Grant Fidelity distribution 5-step and 5-spec QC.
2. True 'Cream of the crop" on Grade A
Grant Fidelity Premium Grade A tube are 'cream of the crop' from Shuguang factory production runs and are verified by extensive testing results. There are very small percentage of Treasure tubes out of the factory that actually quality our Premium Grade A standard so they deserve higher market value and better resale value. Similar to high quality sought-after NOS tubes - they are rare, and they are proven really good. Without Grant Fidelity's stringent quality control, Chinese tubes couldn't have reached today's market status as premier tube manufacturer and compete head-to-head with many best NOS tubes and well established tube brands. Remember, tube quality is controlled not just at the factory, it also must be controlled during distribution.
