Leslie Model 21H

Leslie Model 21H

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

Leslie Model 22H

Leslie Model 22H

The model 122 cabinet is shown at left. The 22H 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, not two as shown here. This model was made specifically for the balanced output of a Hammond “G-G” Console […]

Leslie Model 30C

Leslie Model 30C

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 […]

Leslie Model 31A

Leslie Model 31A

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. What this meant is that the 15″ woofer did not have a permanent magnet, like speakers have today, but rather […]

Leslie Model 31H

Leslie Model 31H

The model 31H was made specifically for the balanced output of a Hammond “G-G” Console (IE Model B or C). I believe that this is no different then the model 31A save for some improvements in the amplifier design. It is at this point (1950) that Leslie adopted a suffix letter to designate the manufacturer […]

Leslie Model 31W

Leslie Model 31W

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”. It is interesting to note that unlike later cabinets, this cabinet featured an ELECTRO-dynamic speaker. What this meant is that the 15″ woofer did not have a […]

Leslie Model 44W

Leslie Model 44W

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.

Leslie Model 45

Leslie Model 45

Like a 44W this cabinet is 33″ in height, it uses a 47 type amplifier and is quite simply a short model 47.

Because of it’s cabinet dimensions it has slightly less bass […]

Leslie Model 51C

Leslie Model 51C

This cabinet’s amplifier is a 2 channel tube type chassis with 2 x 6550 finals in the rotary channel producing 35 watts, and 2 x 6973 finals in the stationary channel producing 20 watts. The 50C was designed for use with Conn organs, but like the other “Conn” cabinets, it can be attached to almost […]

Leslie Model 55C

Leslie Model 55C

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.

Complex voices being defined as non Flute/Tibia tones such as Strings and Diapasons. This model […]

Leslie Model 122N

Leslie Model 122N

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.

Leslie Model 122

Leslie Model 122

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.

Leslie Model 130

Leslie Model 130

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.

Leslie Model 142

Leslie Model 142

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).

Leslie Model 142N

Leslie Model 147

Leslie Model 147

This cabinet is considered to be “Universal” because it can be attached to almost any monaural organ with the appropriate connector kit. It is also used on Hammond “G-G” consoles because of it’s similarity to the 122. While the amplifier is essentially the same as the earlier 47, the 147 replaced the 47 and introduced […]

Missing Models

There may be some models which are missing, and if you have any information about it (or PICTURES!)  I’d love to hear from you.  Just use the contact link to let us know.

Special Note about Hammond Suzuki Leslie’s: I am no longer maintaining information for any models conceived and built following Hammond Suzuki’s acquisition of Leslie including reissue models such as the 122A, et. al.  Beyond being grossly disappointed in the product I am not really interested in staying up to date with whatever their latest thing is.  Perhaps one day, if they should go under, I’ll try to piece it all together.
