Flagship Version 6th Generation HiFi Electronic Tube Power Amplifier 4 KT88 Tube

  

Flagship Version Sixth Generation HiFi Electronic Tube Power Amplifier Four KT88 Tubes Replacement for MC275 Description: - The sixth generation flagship version basically adds a purification module system in the fifth generation, and everyone knows that transformers are one of the most important parts of the tube amplifier. The winding method and material of transformers are of utmost importance. The reason why the tube amplifier for Mcintosh stands out for generations is its unique multi wire parallel winding transformer technology. The replica 275 for Mcintosh has three combinations, one for the power supply and two for the output. A team of experienced Taiwanese enthusiasts has spared no effort in using up to sixteen units (the original 275 for Mcintosh is twelve) UP-OCC (single hydrogen free copper) for grouping and winding.

The purity of the single copper free product can reach 99.99, reaching a high level. After each transformer is wrapped, it will undergo freezing treatment. After low-temperature treatment of the metal, the low-temperature treatment of the conductor can disrupt the crystal arrangement, recombine molecules, and macroscopically make the metal harder.

This type of transformer has the advantages of good broadband response and extremely low distortion, which is similar to the effect of a Mcintosh transformer. Due to the high cost of materials, which weigh up to 25KG, three transformers account for two-thirds of the weight. With such meticulous material selection, winding, and special freezing treatment, the power of the stereo can reach 75W on one side, and 150W on a single channel in series, equivalent to 800W of a stone machine.

It has an open and wide sound field, and listening to large-scale orchestral music is particularly exciting. You can easily feel the distinct layers of voice, the undulating dynamics in the music, the thick and full sound base, and the rich and strong low-frequency, making the music full of power and vitality. There is a problem with the sixth generation flagship bias technology electronic vacuum tube machine, which is the need to adjust the bias voltage of the vacuum tube.

If the power tube needs to be replaced, the bias voltage adjustment is even more inevitable. The traditional bias adjustment involves measuring the value with an electric meter and then using a screwdriver to turn the screw.

Later on, some manufacturers made progress by building measurement circuits and displaying the current bias status with light signals or screen values, making it more convenient to adjust the bias voltage. However, for many consumers, it is necessary to check the bias condition later and slowly turn to the correct position after changing the pipe.

When it comes to adjusting the bias voltage, one needs to heat up the machine. After the machine has been running for at least half an hour and the pipes are all hot, adjusting the bias voltage is accurate.

So it seems that it's still troublesome. Using a self-designed automatic bias voltage adjustment circuit, not only do you have to worry about the bias voltage running away after a long time, but it is also more convenient to replace the tube. If you want to replace any pipes, simply replace them and turn them on.

This 275 will adjust the bias voltage to the correct value on its own. This technology was developed by a Taiwanese team after several years of research, while other 275 products on the market do not have this feature. Package Included: - 1 x Electronic Tube Amplifier. Usually it costs about 30USD-50USD.
