What do I know about Leslies? (not much, I fear)

[gacki@sax.sax.de (Malte Rogacki)]

So I'm taking the next approach and try to give a summary of the first
"Leslie" article from the Hammond series in the german keyboard mag. Again
the author was Dieter Enners.

Leslie 31H: This was the first Leslie built for use with Hammond organs.
One 30-Watts-amp. The case looked different to the later models, with a
larger bottom part. Only one speed.

Leslie 21H, 22H, 23H: Built with the same electronics as the 31H but with a
smaller case (looks almost like the 122). No other info, sorry.

Leslie 51H: became later the 251. I suspect the 51H did only have one
speed, too.

Next came the slow/fast models. Electromusic (the Leslie company) dropped
the "H" suffix from now on.

Leslie 122: You all know about this.

Leslie 251: This one was built like a 122 with an additional 15-watts-amp
that gave power to two oval speakers. This model was intended for use with
the "Selfcontained" models like the A-100 or the M-100. The second amp took
the signal from the reverb unit of the organ, so you got a "non-rotating"
reverb sound in addition. Unbalanced input, BTW.

Leslie 147: like the 122 but with an unbalanced input. This model was built
to be used with a variety of instruments, hence it got a separate pre-amp.
However, it could also be used with an accessory kit similar to the 122.

Leslie 222: same innards as the 122 but a different case. This was directed
to the home-market and had a greater width than height.

Leslie 351: as above but the electronics of the 251

Leslie 246: as above but the electronics of the 147

Leslie 142 and 145: These are the shorter versions of the 122 and the 147.
they were developed to fit the outfit of the (smaller) M-3 organs.

Leslie 125: This is the "low-cost" version of the 122. It has only 20 watts
and the complete treble system (rotor, motor) is missing.


Leslies, that are already "prepared for reverb" (whatever that means) got a
suffix "R" (like 122 R).

Leslies with a separate reverb amp, reverb spring and reverb speakers got a
suffix "RV" (like 147 RV).

Some models were also offered with a black finish as so-called "road
models". They got an "N" or "P" suffix (122 P, 122 N, 147 N) or were called
"combo" (Combo 145).

Leslies usually needed an accessory kit (maybe it is actually called
different) with the switch for slow/fast etc.

Here are a few combinations:


        Organ           Leslie          Kit#

        B3              122             8001
        C3              122             8002
        RT3             122             8001
        M3              142             8010
                        145             7271
        M100            251/351         8253
                        147/145         7271
        A100            251             8253
                        147             7271

If no one minds I would try to compile the informations on the solid state
Leslies, too.

And, BTW, I sent informations about this list to Dave Amels, the president
of Voce Inc. Maybe he will join us, too.
