LSCA-3 includes a 3 position switch and the associated wiring harness, but does not include the halfmoon case for the switch.

LSCA-3 does not require special or individual connectors or adapters for different types of Leslies or Hammond Tone Cabinets .  This means that any LSCA-3 outlet on the Hammond can connect to any Leslie or Hammond Tone Cabinet in your system, balanced or unbalanced, 2 speed or single speed.  Even no speed.  (ie; Hammond tone cabinet.)  No more 147/122 separate outlets.  

The LSCA-3 box replaces or bypasses any existing Leslie adapters.  It provides a straight path to the Leslie amp for signal, ground, and power - there are no components in the signal path.  Motor control switching is completely isolated, and is not performed over the signal cables, as with 122 type adapters.

Because of this, the associated hum, buzz, clicks, pops, and bangs all disappear immediately.  The response time from slow to fast to off is instantaneous.  There is absolutely no volume drop or change when switching speed.  Circuitry in the Leslie amp no longer controls the motors, it is done entirely by the LSCA-3, and the Leslie amp can do what it's designed for: amplify the organ signal.

Unlike most relay replacements, the LSCA-3 provides the player with the all-important STOP (or BRAKE) position.  For many players, brakes are absolutely essential.

Nothing significant is changed or modified in an LSCA-3 installation, except the original Leslie switching circuit no longer controls the motors.  Instead, the LSCA-3 does.  Nothing in the Leslie or Hammond needs to be altered to use the LSCA-3, the motor control circuit is simply bypassed or ignored, and is not connected to the motors.  Because of this, if there was ever a need to "return to stock", it would be a very simple job.

My instruments are used professionally, and I have no tolerance for exotic hookups, wire tangles, extra jumper cords, etc.  My requirements specify one, single, multi conductor cable going to each Leslie.  For that reason, I tried to design a system that would allow me to replace the specific components that have caused problems, and yet retain both function and appearance as closely as possible to an original, stock installation.  LSCA-3 flawlessly achieves that end.  Once installed, it's totally transparent.

Adding Another Leslie

Adding Leslies of almost any type with LSCA-3 is very simple.  All that's needed is another Leslie cable, another outlet on the Hammond, and a chassis connector for the new Leslie amp.  Approximately 30-60 minutes of wiring work, and it's done.  No Leslie adapters, no special hookups, and most of all - no concern with switching.   It's already done in the LSCA-3.  Most LSCA-3 users install additional Leslies in about one hour.

Sum It Up

I've been developing LSCA in several "versions" since I started playing Hammonds professionally, about 40 years ago.  I've tried everything I could find to solve the problems - clicking, pops, banging, and no-response switching, volume drops every time the switch is used .... on and on and on.  Through the years, I've met and spoken with several dozen players who have put up with these same problems and felt like I did.

All of my own Hammonds and Leslies, as well as all of the Hammonds I rebuild and rent, DO NOT use stock Amphenol connectors.  Because of the problems with Amphenols, I don't recommend them, especially for professional applications.

Instead, I use and highly recommend the ridiculously expensive AMP-CPC type of multi pin connectors, featuring locking rings and gold socket and pin contacts.  I have used these connectors exclusively for over fourteen years with no problems at all.  (see associated pics)

These AMP-CPC type connectors are easily the greatest cost factor in an LSCA-3 installation.  For a 3 Leslie system, they actually cost far more than the LSCA-3 control box itself.  I feel they're worth every dollar spent, and would never change back to Amphenols for any reason.
