The Decorator Leslies page 4

 
A close cousin

In the early 70's, Electro Music came out with a new series of decorator Leslies incorporating the technology of the Pro-Line solid state models (see the Pro-Line page). The smallest was the close cousin of both model 245/242 and 225, named model 130. This cabinet did not have a horn, only the bottom rotor would spin, but instead it had a 3" treble speaker mounted on the front baffle.

Side view. The cabinet is almost identical to the 245/242 with the exception of the missing upper louvres.

 

Here is the 130 from the back. Note the metal lower back panel which serves as heatsink for the output transistors of the amplifier. The input plug is 11pin - the current standard for Leslie interfaces. This is why there is a separate power cord for this model.
On the right, a picture of the 130 with the back panels off. The foam rotor, the 12" bass speaker and the 3" treble speaker are clearly visible. On the left, beside the rotor, is the chassis containing the power supply and the motor control electronics for the Leslie. Unlike the larger solid state models, this entry-level cabinet has only one amplifier channel with a passive cross-over (as seen on the left beside the 12" speaker).

This Leslie 130 is installed in a church in Kingston, Ontario in Canada.

 

 

Roto-Sonic decorator Leslies
Another variant of the solid state Pro-Line series technology in a decorator cabinet was the model 700. It is basically a model 710 minus the horn. The sound in this one is more theatre-organ like than other single-rotor Leslies because of the Roto-Sonic rotor.

Model 700 was later updated to the 11-pin cable interface and became model 705. A special version of this for church use was called 705-C and can be seen on the right.

Other decorator models

 

 

  

Electro Music made other models of Leslie cabinets in the 'decorator' line that were not directly suitable for Hammond organs. One example is the model 600 with four amplifier channels (solid state), a Roto-Sonic drum, standard treble horn and four stationary speakers.
