Description
The Defender DC-147 is a modern safety upgrade to any console organ that is compatible with a 147-type Leslie®. Intentionally designed for easy installation, the DC-147 converts the potentially lethal AC voltage on the speed switch to a safe 12VDC.
Installation is as simple as rewiring the speed switch and inserting the DC-147 between the switch and the Leslie 147 connector. Defender takes over pin 2 of a 6-pin 147 connection and taps AC on pins 3 and 4. Every Defender ships with 1′ each of blue, yellow, and gray wire to add to your existing connection, if needed.
BookerLAB offers a few configurations for the Defender, with an option to include a 1-foot 1/4″ TRS jack accessory that can be easily rewired for either 2- or 3-speed usage. Defender can also be utilized in a console as a “connect kit”.

Note for existing Solid State Relay relay users:
If your setup is currently using a Solid State Relay to implement 3 speeds- Fast, Slow, and Stop, then your half-moon switch will have a diode soldered from the Fast lug to the opposite Slow lug. You must remove the diode and connect a wire from the fast lug to the Defender Fast Terminal Block input, or to the Ring terminal on a 1/4” plug.
Todd Phipps –
Easy, straightforward install. Smooth, safe switching, and being able to safely add a footswitch is a bonus! As a player who’s been shocked by a worn 147 half-moon where a stray strand of wire had touched the switch frame, I know well the hazard that can be present with 120VAC on the Leslie switch. This eliminates the hazard and so far has gotten rid of occasional popping when switching in my case. Being able to plug in a footswitch when desired without a shock hazard is icing on the cake! I highly recommend this unit for all implementations of 147-family (6W pinout) Leslies.
