--- Warning ---

Real damage can occur if you connect a Leslie incorrectly. While every reasonable effort has been made to insure these pinouts and the Leslie references to them are accurate, the Service Manual is the ultimate authority on technical matters.


Type 11 (Contacts are numbered 1-11 counterclockwise, looking straight at the female end of the cable or the back of your keyboard, presumably. Index mark between pins 1 & 11.)

Pin # Function in a 900 series cabinet
1 Rotary (brown)
2 Main (if equipped)
3 Aux (if equipped)
4 circuit ground (yellow)
5 control supply common (green)
6 Cabinet on/off (Short to pin 5 to turn on) (blue)
7 fast motor control (violet)
8 slow motor control (gray)
9 n/c
10 n/c
11 +28.5v (white)

Here's the motor speed control table:

motor mode short pin #5 to:
off pins #6 only
slow pins #6 and #8
fast pins #6 and #7


Type 9 This is the most dangerous one because there are so many different pin assignments there is almost no standard 9 pin connection.

(Pins are numbered counter-clockwise, viewing the rear of the male connector. Index mark between pins 1 & 9).

Pin # Function in a 900 series cabinet
1 Ground
2 Signal input
3 No Connection
4 Reverb/Aux control. Goes to ground, ground thru a diode, or open.
5 +28V out.
6 Goes to ground for FAST.
7 Goes to ground for SLOW.
8 120V in.
9 120V in.


Type 6A (Pins are numbered counter-clockwise, viewing the rear of the male connector. Index mark between pins 1 & 6).

Pin # Function
1 Ground
1 balanced input signal
2 gnd
3 117VAC input
4 117VAC input
5 310VDC Output (through 10kohm) for control voltage and early Hammond preamps
6 balanced input signal

Bias pins 1 and 6 to 70V for slow speed, gnd for fast. This must be done through an R-C network to develop a .5 to 1 second time constant to prevent switching transients from coupling to the input stage of the amplifier. If you do not understand the above statement, consult with a qualified service technician.


Type 6B (Pins are numbered counter-clockwise, viewing the rear of the male connector. Index mark between pins 1 & 6).

Pin # Function
1 Ground
2 117VAC to relay solenoid
3 117VAC input
4 117VAC input
5 117VAC to relay solenoid
6 unbalanced input signal
