No.16.2 is a style of top-grade one. At final stage it uses directly heated tubes,300B as single-end amplification, and it uses 6SN7 as pre-amplification. Without total loop feedback, its transient intermodulation distortion is very low. Its output power is 9Watt.The transformer of No.16.2 can be called as ¡°a masterpiece¡± that has been designed by the designer of the Beijing Yushang Co. The silicon steel sheets its transformer adopts are high silicon orientation ones with minimum magnetic induction intensity 1.9T. On the aspect of dynamic and static test, special coil structure and method of winding make the transformer exceed some of the most excellent ones existing in current world.
To protect the tubes and the unit, as well as to ensure tubes¡¯ service life, it has a testing system for final stage plate and a tube-usage-time display system. And an earphone socket can be used if you like. Any component and its design show the characteristics of uncompromisingness that a top-grade amplifier has.
No.16.2 continues to use the creative sandwich structure that designed for No.16.0, with aluminum plate 10mm in thick, which looks dignified, luxurious and rich in connotation. The layout of the three transformers is inverted pyramid in shape and also its weight-distribution and thermal-distribution are quite good.
The sound performance of No.16.2 is full, rich clear and meek; fully show the special magic power that a tube single-end amplifier has.
