    Is it absolutely necessary to use the PSA series AC Adaptor for the Boss TU-3 tuner?

    Not sure what the PSA series is exactly, but I've used a bunch of different adapters on my TU2 - one spot, yorkville, ibanez - everything has worked fine.

    Nope, not necessary. As long as you are using a 9v center negative tip adapter with at least ~50mA of available current, you should be fine. I don't remember the exact the current draw of the pedal but I don't remember it being very high.

    The PSA standard is just like a conventional regulated 9V pedal power supply so any regulated 9V DC power supply will work fine. The old Boss pedals w/ the ACA standard I think involved a 12V unregulated supply and regulation and voltage step down was done inside the pedal.

    Cool, so I have an adaptor that says INPUT:110V 50/60Hz OUTPUT: 9V 350mA will this do?

    Yeah, assuming of course the output is 9V DC not AC, and ideally regulated (otherwise you could have noise).

    Cool, yeah it says AC-DC Adaptor, but I'm not sure which is which, but this is the lowest adaptor I have, and I just don't have the extra money to go buy one.

    To be safe why don't you post the brand name and model # of your adapter. That way one of us can research it for you to be sure.
