This belt is a direct replacement for the “gray” belts used in all our current Leslie speakers. This belt is used for both the upper and lower rotors of the Leslie. A quick way to determine if your Leslie is of the current type is to examine the Leslie motors present in your Leslie. Current Leslies use one motor to control the slow and fast speeds while vintage Leslies requires two motors. We recommend that a factory-trained technician install this part.
