About BoyuuRange REISONG A50 MKIII 300B HiFi Intergrated
Regarding the hum (ground noise), the vacuum tube amplifier has very high requirements for the power supply. And it is very susceptible to interference from other electrical appliances around, especially WiFi routers. If you have humming or other noises on both channels, you can try to turn off or remove the electrical appliances near the tube Amplifer that may affect it. Features: If you listen the BoyuuRange A50 MKIII Amplifier, you will know 300B is good at bass too.
