hello, Transformer hum is caused by the power supply. If there is a DC component in the power supply it can cause transformer hum. It is sometimes loud and sometimes small and sometimes disappears. This is very common phenomenon. Cengrand's transformer design adopts a low voltage regulation scheme, which can bring better performance and sound quality, but it is sensitive to AC power. It is very different from transformers with high voltage regulation rates. In recent years, we have encountered some feedback from users about transformer humming, and the problem has been resolved. We can also replace the transformer with a high voltage regulation rate, which is cheaper. But in order to ensure sound quality, we did not operate in this way. We have increased the cost of after-sales service for this, but the sound quality of our products has always been guaranteed. Additionally, you can add a DC eliminator. We also have such product for sale. This is an effective way to solve the problem.
