Hello, I have the same problem. But I am listening to music from the turntable. Even though the chassis cable coming out of the turntable is connected to the amplifier, the same problematic sound still comes out. I changed the transistors, the problem was not solved. I changed the needle of the turntable, the problem still persists. I wonder how I can solve this.
Good tip, thanks
