Again, this system found it’s way onto other organs, for example the Hammond A-100. This was done to accommodate Conn’s two channel organs. Wiring has been rearranged to allow two audio inputs instead of one. Dual Channel Interface (AKA CONN) Actually a derivative of the Unbalanced interface. Where an “Unbalanced Interface” model can be driven by an amplifer, Amp Driven cabinets need to be driven by an audio amplifier’s output in order to be heard. Amp Driven Interface This is my way of differentiating between amplified cabinets such as the 147Īnd un-amplified cabinets such as the 110, 112, 114, 116, 120, 120C, etc. which uses the same pin arrangement but required a different audio signal to operate.
Models without power amplifiers have the speaker(s) connected directly to pins 1 and 6 NOTE: Early models could be ordered without a power amplifier. Interface is sometimes referred to as Universal. Unbalanced Interface (AKA Wurlitzer) Designed so that Leslies would be compatible with Wurlitzer organs, later these models were used on a wide variety of organs. They must be connected to a Hammond Tone Cabinet socket unless they are modified by the addition of blocking capacitors on the input, or one of Leslie’s original adapters (NLA) is installed.
WURLITZER ORGAN MODEL 950 SERIAL NUMBER
NOTE: Early “30” series models below serial number 5200 were not designed to be used with a console connector kit. Balanced Interface (AKA Hammond™) For Hammond™ Organs because of their balanced output. There were three versions of this system,Įach for a different family of tone cabinets.
Since a 5 pin plug to 6 pin socket cable is used in the above applications, I have provided the “6 pin” column below to illustrate the wiring of one of these “5 to 6” cables. In these cases the “extra” pin is simply left open and unconnected.
WURLITZER ORGAN MODEL 950 UPGRADE
Connect Hammond™-type Leslie™ models to later Hammond™ Organs (-2 and -3 models among others) via 8000-type connector kits and five-pin sockets at theĭespite all these applications, the 6 to 6 cable is far more common and is recommended for new work and as an upgrade to older instruments.“Daisy-chain” older Hammond series (21H, 22H, etc.) Leslie™ Cabinets.Connect Hammond™ tone cabinets to later model Hammond™ Organs which no longer needed the B+ supply from the cabinet.This system was originally designed by Hammond™ to:
Pay special attention to the model’s listed in each section, as there are a number of Leslie™ models out there with “nonstandard” interfaces. This document covers the 5, 6, 9, and 11 pin STANDARD systems used by Leslie™.
