The Leslie 147 Speaker Cabinet is a traditional two-speed rotary speaker with a warm, swirling tone. The distinctive chorale and tremolo effects are produced by a 40-watt tube amplifier, a revolving 15″ bass woofer, and a horn driver. It is a favorite for vintage organ and keyboard setups because it has an unbalanced 6-pin input and produces a slightly brighter sound than the 122 model.
