Unit should include a special crossover assembly, foot switch, and adaptor to connect it to a guitar amplifier. See our schematics section for details. 16 and 18 are identical except for the fact that the model 18 has a full range JBL speaker. These units are the same as the Fender Vibratone cabinet.

The model 122 cabinet is shown at left. The 21H cabinet is very similar in appearance to a 122 or 147, the largest difference is that the upper horn speaks through only one level of louvers.

This is the “Church Version” of the original Leslie Model 30A, a single speed cabinet with no provision for remote control. It is supposed to have had a different rotational speed. “The church models definitely ran at a different speed. The idea here was that the standard Leslie tremolo was deeper than that of a … Continue reading Leslie Model 30C →

The model 31A was made specifically for the balanced output of a Hammond “G-G” Console (IE Model B or C). It is interesting to note that unlike later cabinets, this cabinet featured an ELECTRO-dynamic speaker.

The model 31H was made specifically for the balanced output of a Hammond “G-G” Console (IE Model B or C).

It is at this point (1950) that Leslie adopted a suffix letter to designate the manufacturer … Continue reading Leslie Model 31H →

This model was made specifically for the unbalanced output of a Wurlitzer console, although it could be adapted to many other manufacturer’s organs with a “Console Connector Kit”.

The model 44W was made for Wurlitzer organs, although, as with all the other “Wurlitzer” cabinets, it could be used on almost any monaural organ with the appropriate connector kit. The 15″ woofer in the cabinet is most likely ELECTRO-dynamic. Please see the model 21H page for details on this type of woofer.

Like a 44W this cabinet is 33″ in height, it uses a 47 type amplifier and is quite simply a short model 47. This cabinet is considered to be “Universal” because it can be attached to almost any monaural organ with the appropriate connector kit. Because of it’s cabinet dimensions it has slightly less bass … Continue reading Leslie Model 45 →

The 55C was designed for use with Conn organs. Unlike the other Conn cabinets this one can not be so easily used with other organs. This is due to the fact that in these cabinets, tremolo switching was accomplished by switching audio channels.

See model 122 page for specifications. The 122N is exactly the same as a 122 electronically. These cabinets were made at the “Hammond” factory in Anvers, Belgium following Hammond’s acquisition of Leslie. I gather the design change was to make this cabinet more appealing to European customers.

This is perhaps the best known of the Leslie models, introduced in 1964 it replaced the single speed 22H and became *the* cabinet for use with the Hammond B3 organ. While the amplifier is essentially the same as the earlier 22H, the 122 replaced the 22H and introduced 2 speed operation (Tremolo and Chorale). This … Continue reading Leslie Model 122 →

Single channel, single rotor cabinet with internal amplification.  This cabinet is somewhat odd in that in addition to it’s 12″ rotor speaker there is also a stationary tweeter on the rotary channel. According to the manual, the 12″ speaker handles frequencies below 400 hz and the tweeter handles frequencies above 4000hz – leading to the … Continue reading Leslie Model 130 →

This model uses a 122 amplifier and is essentially a short 122. Because of it’s cabinet dimensions it has slightly less bass punch then a full sized cabinet like the 22H or 122. This model was made specifically for the balanced output of a Hammond “G-G” Console (IE Model B3 or C3).

Similar to the Model 310 it had the same sound system, packaged in a furniture finished cabinet. Few if any were sold in the USA.

The 315 is an older “Pro-Line” cabinet, meant for road applications. It has both rotary and stationary channels, and is packaged in a road cabinet with castors and handles to make it more portable.

This is a smaller version of the 760, and intended for use with a combo preamp. Some organs, especially today, already have a Leslie connector built in and can connect directly to this Leslie’s 11 pin connector.

The 350 was designed exclusively for use with Conn organs.

The model 351 is the same as a 251, it is simply repackaged in the “Decorator Style” cabinet you see here.

The 412 is a profession type cabinet meant to be used “on the road”. It features 1 rotary and 2 stationary channels and an 11 pin interface. (See also Model 412J.)

The 412J is the same as the 412 functionally, but internally it is *very* different. This cabinet, which was made in Japan, has NO parts that are interchangeable with a 412 (which was US made).

The 415 is an adaptation of the HL-422 cabinet. This model has both stationary and rotary channels an it is intended for use with most 2 channel organs, through the appropriate connector kit. The HL-422 was originally sold only with B3000 organs and has coners that match the B3000 cabinet. The 415 is the same … Continue reading Leslie Model 415 →
