Description
The Double Speed circuit allows the implementation of the slow speed in Leslies which lack it, such as the 21H, 22H and 31H.
The slow speed can be tweaked thanks to a 4-position jumper placed on the board.
The original relay is discarded, resulting in the loss of the distinctive “click” sound heard during the change in speed.
The circuit is mounted inside the cabinet, an easy installation that doesn’t alter the appearance of the speaker.
