LINE VOLTAGE SELECTION FOR THE UC-1A:
The UC-1A is available in both 110/120 volt and 220/240 volt versions. However, since the AC power supplied to the UC-1A is passed along to the Leslie 6 and 9 pin connectors, the UC-1A must be ordered with the same voltage rating as the Leslie speaker(s) being used.
