HIFI 2.0 6N8P Replaces 6SN7 CV181 6H8C Vacuum Tube Preamp WY3P 5Z4P Tube Rectifier Tube Preamplifier Amplifier Audio
The high frequency is delicate,
the low frequency is powerful, and the mid frequency is mellow! The
effect of replacing imported brand electronic tubes is obviously
improved.
●All
parts of this product are original, unpretentious and pure in quality;
using high-quality original parts is not only a guarantee of safety and
quality, long service life, but also a strong guarantee that the actual
performance can reach the design goal.
●The resistance adopts five-ring metal resistance, and the high-power resistance adopts oxide film resistance.
●PCB
adopts 1.6mm thick double-sided board, 1OZ (35um) copper thickness, and
full tin spraying process to ensure good passing performance of large
and small currents. PCB quality. The PCB design strictly follows the
principle of one-point grounding. The layout of the wiring in the box is
reasonable and orderly, and the power lines and signal lines do not
overlap and overlap, effectively reducing the chance of mutual
interference!
●Adopt
5Z4P (can be directly replaced by 5Z3P, 5AR4, 5U4G, 5U4C) tube tube
rectifier, high voltage power supply, resistance step down to increase
the pressure difference, provide stable and pure DC power supply for the
front stage, more suitable for use in areas with large power supply
fluctuations.
●The
tube filament 9V AC rectifier is regulated to 8V DC, and then the
resistance is stepped down to 6.3V. Combined with a point of grounding
and reasonable wiring, it is economical and does not produce hum.
EI8645
power transformer (power 100W; no heat, pure copper wire winding.
Inductor (EI66X28) current is 100MA 20H, large inductance, obvious
filtering effect, elastic sound quality, speed is less soothing than
inductance, the bottom noise of the whole machine is 1MV about.
Standard
electronic tube: rectifier tube Soviet Union 5U4C, amplifier tube:
Dawning 6N8P (can be replaced by imported tubes such as 6SN7, CV181,
6H8C), voltage regulator tube is Hangzhou WY-3P
●Circuit
characteristics: strong taste of bile, very sweet and warm sound
quality, high density of intermediate frequency (voice)!
●The
high-voltage filter capacitor adopts ruby 150UF + Nippon Chemical 33UF,
and the output coupling adopts Hong Kong TE MKP film capacitor 0.68UF +
4900P in parallel; if the capacitor is replaced, the sound quality will
be significantly improved.
●Adopt
Japanese ALPS 100K 16-type volume potentiometer, without the noise of
other brand potentiometers, and it has a long life and durability.
●Ash wood case version, width 300MM, depth 250MM, case height 65MM, whole machine height 155MM,
The weight of the whole machine is 7KG
[The
input voltage of the machine can be changed to 110V/115V/117V and other
values of voltage. Please leave a message to explain the required
voltage when taking pictures. The machine needs to be changed within 4-5
working days after taking pictures.]
