3.8MK product introduction:
The overall upgrade of Purer3.8MK includes the following major changes:

With the concise and best hi-end design concept, the circuit is optimized comprehensively, referring to the famous power amplifier in Europe, the selection of materials and the rationalization of the circuit are emphasized, and the attention to detail and careful tuning are made to achieve the exquisite music playback effect.

Improved hardware technology, exposed radiator arc design, beautiful lines.Adopt special structure, the screw can not be seen on the front of the cover, the whole is more beautiful.

 After the use of a new circuit, symmetric difference, constant current source load, circuit simplicity, excellent performance.

The field effect tube is used for the power output tube, and three pairs of acoustic nominal tube J200/K1529 are used for parallel output.The field effect tube is a voltage control device and has a negative temperature characteristic. The push stage and temperature compensation circuit can be more concise with less signal distortion and loss.The replayed music is more realistic and full of details.With the gallbladder level, bring out the best in each other, the overall performance more gallbladder machine charming charm.

Power supply is the source of the beautiful sound of power amplifier, and transformer is the key of the beautiful sound.This time carefully calculate the energy distribution of each part.Transformer is more with sufficient material, A - class iron core, high - quality copper wire.Make every effort to supply small resistance, rapid response, abundant energy.Transformers are also required Less electromagnetic interference, less mechanical vibration.

This machine can be used as merging machine or before and after stage separation, this change is: as merging machine, no external connection signal line is used (the machine has been connected).The function switch is installed in the rear panel, and the corresponding indicator light is displayed on the panel to avoid operating errors.

Circuit features:
1. the front and rear stage separation design: this machine can be used as a combination amplifier of the front gallstone, and can also be used as a single high quality gallstone front stage or the back stage of a set of transistors, a multi-purpose machine, increase the fun of playing hi-fi.

2. Front gallstone circuit design: the front stage adopts the technology of "absolute linear audio amplification" patented in China, and realizes linear amplification with the vacuum tube. Without relying on negative feedback, the distortion of the circuit can be very small, so the transient characteristics of the circuit are particularly excellent, and the details and emotions of the music can be truly restored.

3. Reasonable structure and layout: the case of the machine is very solid, and the heat sink and panel are made of thick aluminum alloy, giving people a sense of weight.The solid and stable fuselage has good shock absorbers, and the ju machine foot will further effectively absorb shock, laying a good foundation for the stunning sound of the power amplifier.The layout of the machine is very reasonable and beautiful. The circuit part and the transformer are separated and isolated by thick iron plate.The circuit is distributed in the back part, and the two power transformers are located in the front part without interfering with each other.Similar to the design of the power splitter, it makes the music level clearer and the sound field more accurate.

4. components selection: this machine USES a variety of advanced components, including military-grade ultra-small vacuum tube, France Solen coupling capacitance and Germany weimar MKP10 capacitance, sound rich ELNA capacitance, Toshiba J200 / K1529 field effect tube, advanced non-oxygen copper connection, gold-plated lotus input terminal.

5. balance input and remote control function, in line with modern taste, is a comprehensive pursuit of hi-end amplifier.
