    Hi there,
    A friend has just purchased a new Hum Debugger and it has arrived with a 110v/60Hz PSU – not ideal. I have a collection of _similar_ PSUs that can output 7.5v 400mA, but the tip connector is not the same (does not fit). Can I use this and replace the tip with one on the original US EHX Hum Debugger PSU, or would this be a grievous mistake?

    I’ve been able to find a unit on Reverb (https://reverb.com/item/30889615-electro-harmonix-hum-debugger-power-supply-ac-adaptor-uk-version-new-with-full-warranty)

    NZ standard mains power is 230V at 50Hz. I am guessing that a UK EHX PSU (like the one shown above) will output a slightly higher mA output (418mA vs 400mA) and that this should not pose much of an issue. If I can safely bodge together a solution with what I have to hand, then I am all for trying it, but I am keen not to let the smoke out.

    Casio PSU - would it work with a Hum Debugger?

    I look forward to hearing from you. Thanks!

    The power supply MUST be an AC out supply.
    Not DC out like most pedal or keyboard supplies.
    It needs AC out to sample the current to operate the notching circuit.
    The link you show for the UK supply is correct.

    Again ONLY an AC out supply at rated specs.
