You can always email Furman and see if it's even possible to power an Eventide box out of those 9 v plugs, maybe by using some special power doubling Y cable. Timefactor is pretty demanding powerwise, people complain of units failing to start up or that the delay doesn't sound as good when underpowered. Voodoo Lab Pedal Power 2 can handle 1 eventide box using a Y cable. That seems to be the official answer around. T-Rex has a power supply that works too.
The adapter works perfectly. Use that.
