                                         Tremolo Switches

The switch pictured above was an early half-moon switch that was used to switch the Leslie rotors on and off in the early model single speed Leslie speakers; 31-H, 21-H, 22-H, 25, 42-H, 45, 47 etc...

Back in the early Leslie Speaker days, there was only a single motor for the bass rotor and one for the upper horn rotor; therefore, only an on and off switch was needed to make or break contact with the motors.  This switch as with the newer switches, gets mounted on the front of the lower manual rail.

The switch pictures above is for the later 2 speed model Leslies that had the 2 speed motor assemblies model 122, 122RV, 222, 222RV, 145, 147, 147RV, 247, 247RV etc...

The picture above shows a typical Leslie speaker installation kit for the model B3/C3 organs.  Although the installation kits for other Hammond models varied slightly they were pretty much the same.  The only difference was the Tube socket adapters were octal base for older models or they were hard wired.

Pictured above is what was called an echo kit; this Leslie installation kit was used with smaller spinet organs or single channel consoles that had internal speakers and amplifiers.  You had an extra selector switch to select between the internal organ speaker or the (echo) Leslie speaker; or you could have both playing at the same time for effects.  This kit could be used with the Hammond models M2, M3, A100, M100 or any other single channel organ.  This kit was mainly for the model 145, 147, 147RV, 247, 247RV, 120, 125.

Above is a picture of a Leslie Upper Horn Rotor; this is what produced the highs from a Leslie speaker.  Only one side was operable, the other horn was a dummy just for rotor balance.  Plastic diffusers were used to deflect the sound so it wouldn't have the harshness of the direct sound.

These are the slow speed motors that were used in most 2 speed Leslie speaker models; 145,    147,147RV, 122, 122RV, 247, 247RV, 222, 120, 125 etc.

Pictured above is the Amplifier that is used in the model 122, 122RV, 222.  It's power output is 40 watts and uses a DC relay for switching the rotor speed from fast to slow.  Tube used in these amps are 2 6550, in push-pull for the final output, 2-12AU7 one 12AU7 was the pre driver for the output tubes and 1/2 of the other 12AU7 was used for switching the motor control relay. 

Above is a shot of the speakers used in almost all larger Leslie speaker models they have an impedance of 16 ohms and is 15 inches in diameter.  The original speakers used in earlier models were made by Jensen and later models were made by Eminence. 

Above is the cable that is used for most Leslie models there was a 5 & 6 conductor cable for the models 31H, 21H, 22H, 145, 147,125,120 etc.  There is also an 11 conductor cable that is used in the newer Leslie 122 speakers and the earlier proline portable models.

These are the bearings that are used in most Leslie speaker rotors; left is the upper rotor bearing, right is the lower rotor bearings.

These are the belts that are used in all Leslie Models.  The white belt is for the Lower bass rotor, and the thin blue belt is for the upper horn rotor.
