    ** Is anyone here unfortunate enough to have experience servicing Fender
    Passports ?

    In particular, the Passport PD250.

    All of them are horrible (Chinese made) things, but this one has a trap for
    first timers.

    The SMPS will not start if you use a variac to ramp up the AC supply.

    So, if you are told that a unit does not operate and do the usual bench test
    with a variac first - the story seems confirmed.

    Big mistake.

    ** I understand that most techs here feel the same as you.

    Fender Australia have big trouble finding ANYONE prepared to do warranty
    service on them.

    Particularly as the max fee allowed is that for one hour.

    I've repaired 3 Mark Bass, that have not bounced back . At least from a
    combined effort on this board a while back , we now know the workable
    identity of the ground-off PS supervisors as being IR2153 or pinning
    equivalent. I'd prefer Mark Bass to Yamaha StagePas as at least a bit more
    space to play around in.
