Mcintosh MC50 Single-ended Pure Class A Gold seal field effect Tube output HIFI Amplifier
In early 2017, We got a damaged Mcintosh MC50 mono power amplifier. After repair and repeated testing, We modified several components and parameters to make the current machine. After all, the MC50 was an early product. At that time, due to the limitations of the production process and quality level of the components, this machine seemed simple and crude. Although the appearance and workmanship were rudimentary, the sound of this machine was not simple. These early machines continued the tuning trend of the original electronic tube circuit, and the sound was mellow and warm.
McKinton, which is unique in audio products, uses exclusive output transformers for both tube amplifiers and transistor amplifiers. There are many advantages in using the awesome output, mainly to ensure that the transistor can work in a more reasonable linear region when working under different frequency music signals, and the frequency characteristics and phase distortion of the output signal are low, which is an important part of ensuring the sense of hearing. But at the same time, it is quite difficult to produce such an output, which is why no one has tried it in the DIY circle for many years. After comparing different samples of several companies, we have selected the current partner, and there is basically no difference in comparison with the output of the original machine.
Working conditions and functional configuration of the whole machine:
1. Power supply voltage: 220V (110V version can be customized)
2. Main voltage 45V, transformer power 150W
3. Filter capacitor 100v10000ufx4
4. Total weight: 12.2KG (with package, the express fee is charged at 13kg)
5. Power: 10.5WX2@8 Euro
6. THD: 0.005%
7. Frequency response: 20-22000Hz
8. Size: 320X120X310
Special note: This machine is pure armor, and its own heat loss is high. After working for a long time in summer, the temperature around the radiator can reach about 50 degrees, which is normal!
