Hello, I would like to ask for your help to solve a problem with my Yamaha S301 amplifier, which is blinking but not working anymore. Thank you very much. Best regards.

    Hello doctor, on Yamaha amplifiers there is an orange capacitor rated at 600 volts or 650 volts 22uF which pairs with its performance. There is a tutorial on YouTube hoping it will solve your problem. Have a nice day, titi.

      Hi.

      This Yamaha audio amplifier S301 has a transformer symmetrical direct current power supply, not a switching power supply where you indeed find this kind of high voltage capacitor (390 volts) after rectifying the primary (230 volts)

      See you later . . .

      @Doctor: I will reply to you a bit later in PM . . . See you later

        Hello, you can find capacitors on eBay or Amazon. I ordered some for a Panasonic home theater 180 mug 400 volts and 10uf 400 volts. Regards, titi.

    Hello.

    On this amplifier, there are 3 LEDs. Pure direct - Input control - Power. We assume it is the Power one that is flashing. Please confirm.

    In the immediate term = disconnect the speakers and try again.

    See you...

      Hello jojolaguitare, it's the power LED that is blinking. I already unplugged the speakers.
