  Has anyone being using PoweFactor for Modfactor ?
  
  How can 400 mamps of one output satisfy the 1200mamps of Modfactor ???
  
  And what about midi??? Since you midi hook pedals they demand for more current…..

  It has more to do with power, or Wattage, where, Watts = Volts*Amps. The Factors have regulators that can handle 9-12 V. of input. The orginal supplies were 9 Volts, 1200 milliamps, whereas the powerfactor delivers 12Volts, 400 milliamps. The orginal supplies were a bit over-spec'd on what they could deliver too. Most of the demand for current is on powerup, and the specs are fine for MIDI (we've checked).

  So you recommend that we have to plug the Modfactor in the 12 volts output of power factor if The output at 9 volts delivers 400mamps?
  
  Is this safe?

  You should certainly use the 12V output on the PowerFactor for the factor pedals. Like I said before, the right power (wattage) is what matters. The lower current (400 mA) implies you need higher voltage.

  The PowerFactor gives 12V regulated, which means it does not exceed 12V, so this is safe.
  
  Note that an unregulated 12V supply could give 15V or more at times, which is not safe.

  When viewing the spec sheet, all the stompboxes are shown to draw 1200ma each, but the photos show "500ma". I have a Rocktron power supply (about the size of a mobile phone charger) which will handle upto 1670ma. So, could I power 3 Eventide pedals or just one?

  Please look at the many previous posts on this subject. Sigh.
  
  Or, to save you the trouble .. the spec sheet correctly says that the Power Supply is (over)rated at 1200mA – this is to ensure cool running, long life, and reliable operation at low line voltages. The units themselves typically take 300-500mA, depending on voltage. This would suggest that your Rocktron power supply might do it. Some things to note:
  
  1) Damage caused by non-Eventide power supplies is not covered by the warranty.We neither recommend nor support the use of non-Eventide power supplies.
  
  2) Incorrect operation caused by non-Eventide power supplies is not covered by the warranty.
  
  3) Some switching supplies can add noise or buzz to the output.
  
  4) Any supply over 9V MUST be regulated, otherwise it is likely to cause damage.
  
  5) Running multiple units from one supply can create ground loops and cause great HUM !!
