The model number for my VR's power supply is PS0913B. The same model number is used for the Digitech Midi Vocalist as well.

There are two options with power supplies:

1. 9.75-VAC @ 820 mA

2. 9-VAC @ 1A

For some strange reason, Digitech used an AC power supply instead of the conventional DC power supply.

Good Luck,

Gary
