Electro Harmonx soul food maybe burned

  • Hi, few days ago I have plug a multi purpose ac adapter with my eh soul food. Maybe was wrong polarity, by the way, now the pedal doesn't work. The led is on and moving pot you can ear tone variations or hum going up and down , but no sound coming out. Looking inside seems nothing burned, Except 2 capacitors (Yellow arrows) that seems having a little hat , but I don't know if is that their real SHAPE .
    Before try to remove capacitors and plug new one I ask to you if someone knows what usually break in a typical pedal like this in case of [Blockierte Grafik: http://i57.tinypic.com/108io10.jpg]inverted ac adapter. Ty

  • Hi,

    always hoping, that the simplest and cheapest component ist damaged! - No Sir, these caps are the last which will quit...

    Check D4 (it's a 12 V Zener Diode) for its regular function. And measure the voltage at C22.
    U3 is a voltage doubler - Maybe this one was damaged by reversed polarity.
    But how will you desolder and test this SMT device?

  • Thank you very much x answer. Sure it's difficult to desolder this kind of pedal but I will try due it's broken. I will check as you write, maybe I will need to ask again. Thank you
