IMPORTANT NOTE REGARDING 220/240 VOLT LESLIES IN THE 147 FAMILY:

Some 220/240 volt Leslies in the 147 family were manufactured with a 220/240 volt tremolo control relay, while other 220/240 volt Leslies in the 147 family used a 110/120 volt tremolo control relay!  The UC-1A can be configured to work with either type. However the relay voltage of the particular Leslie MUST be determined before ordering so that the proper version of the UC-1A can be provided.

Most 220/240 volt 147 amplifiers have a sticker identifying the relay type.

If you can not locate an identification sticker on your amplifier, it will be necessary to look under the chassis and read the input voltage which is printed on the actual relay.
