Since
the introduction of manual scaffolding and wiring, this stainless steel
tube amplifier has been popular with the majority of fans and audio
enthusiasts. Each tube amp is an original product designed with care.

of hearing. An old song makes people never tire of listening to it, and
it can perform well with full-range speakers and vocal string music.

music can also have good results. This tube amplifier is completely in
accordance with the traditional circuit tube rectifier CLC inductance
filter, and the fixed components of the scaffolding bar are carefully
wired and welded by hand. Each machine can be individually customized
for you. The delicate handwork and beautiful sound makes it your
collection and best gifts for your friends.
The noise level of
this machine is mostly between 0.5 millivolt and 1 millivolt, and the
volume potentiometer can turn down to a low level. Only when your ear is

noise after it turns up has a lot to do with the signal cable used and
the quality of CD. It is not the noise level of the machine itself.
