The treasure tube
series is make specially for 50th anniversary. The
Shuagang treasure tube is black, with "High Polymer
Compound Carbon (HPCC) coating , for the first time used
on vacuum tube production. Compared to traditional carbon
spray technology, HPCC coating will allow greater
concentration of electrons, enhance and maintain stability
of the electron flow, maximize "secondary electron
emission suppression" from the glass enclosure, in turn
reduce effects of electron swirl which generates internal
noises from the vacuum tube itself."
The "standard grade" tube, individual pack in single box, in
our opinion is already very good. It perform exceptional
well in the highs. The instruments timbre is very real.
In Grade A version , the tubes are the best 10% of their
production lot match to a closer tolerance. Local users
has upgrade the tube in their amplifier has report a mark
improvements over the NOS tubes.
