FYI
Despite published specs, the CAE/MXR MC403 *WILL* power the Eventide stompboxes.I have been successfully powering 2 Eventide pedals from the MC403 adjustable outs (set to 9vdc) continuously for the past 5 days. The MC403 gets a little warm, but not too warm to touch. The MC403 specs are very conservatively rated, and while the Eventides ship with 1200ma. power supplies, current draw is only around 350ma.
DO NOT TRY TO POWER THE EVENTIDE PEDALS FROM ANY OTHER OUTPUTS OTHER THAN THE HIGHER CURRENT CAPACITY ADJUSTABLE OUTPUTS (SET TO 9VDC)!!
The other alternative is a AC/DC converter box to convert the 800ma 9VAC outs to DC. This works fine as well. All that is needed is a bridge rectifier/ filter cap (2200uf/ 25V works well) combination to make this work. Granted, this is more complicated, but do-able. The only other thing to keep in mind is cable polarity. The Eventides have 2.5mm x 5.5mm pin (+) barrel connectors, and the MC 405 adjustable outs are 2.1 x 5.5mm pin (-). You can easily modify the cables that come with the MC403 for this purpose.
