QuadVol part list

This is the list of electronic parts needed for this circuit. Note that the links to suppliers should help you to find the right components. However we have no control over their inventory. Therefore it is possible that some of the parts are not available anymore or (even worse) some parts have been changed. Therefore it is important, that you check again that you order the right components.

      Hi Andreas,

      I guess, I did not find a source for that small value. Check if the diameter fits. If the diameter is ok, it is not a problem to use the 22uF/50V capacitor.

    Hello, there is a diffece for the resistors r8,r9,r10 between material list and the wiring diagram ( here (r1,r2,r3) 47 k instead of 1 k in material list and pcb layout)).
    What is the right value ?
