Hey man! Thanks very much for your kind words! Let us know if we can help you with a Hammond for your home, church, or studio. We have a few custom portable units made from actual B3 parts!
That was time well spent. Just a FYI regarding the Doppler effect, the pitch actually does change. The sound waves compress as the horn approaches the listener shortening the wavelength and slightly increasing the pitch and then expands as the horn distances itself effectively lengthening the wavelength and therefore lowering the pitch, that is the reason for the variations in the pitch.
I like it too! What else do you like about our videos and might you have some suggestions for us? We have learned a great deal over our 55 years in business from good people who have made suggestions. We have often requested that suggestions be made by those of good intent and good will. We are always grateful for new good ideas and know that we need all the help we can get!
I'm not a keyboard player, but it was a very pleasing lecture. I always liked the Hammond sound as I grow up listening to Focus' Thijs van Leer and Jimmy Smith playing👍👍👍
My father owned a Hammond B3/Leslie and it got passed on to his granddaughter. It still works good. This brings back memories or Dad who passed last year at age 96.
What's interesting is, from day one through the late 60's, Jensen was the stock speakers used in the 122. When CBS took over Electro Music, they switched over to using Eminence speakers. Eminence was easy to identify by the square magnet on the bass speaker. They were an affordable speaker for OEM and sounded good, but I do notice that 122's that have Jensen bass speakers have a more solid and tighter bass response. That's why when I get a 122 in for repair and it has a Jensen Bass speaker, I always recommend leaving it in there. If it's defective--open voice coil or a rubbing pole piece, I rebuild the original Jensen rather than replace it.
The Leslie has 2 components that spin so that it sounds more realistic like the Pipe Organ because the Hammond was originally designed as a less expensive alternative to the Pipe Organ.
Let me add to Jim's reply if I may. The upper driver found in most older models of the Leslie 122 is the Jensen V21. The lower bass woofer that is found in most 122 Leslies is the Jensen C15L. You will often find a Jensen P15LL in the 22H Leslies.
You are welcome! Hope it helped! FYI we are interested in finding and purchasing this model Leslie should you or anyone else have one of some for sale. If you do, please send details including location and a few pictures to B3buyer@aol.com
Great presentation. I have a question though. In my studio i have a small Hammond S -6 that was given to me by a local Gospel Church. While it has a more restricted range than the B series, i want to know if its possible to somehow connect a Leslie into this organ? This organ is great for adding fill and range on recordings with other keyboards more up front. The Leslie could offer more tone to the sound. Ive seen guys even plug their guitars into Leslies so, there must be a way possibly? Thanks, keep up the informative vids here !
I just bought a 1957 M-3 paired with a 44W Leslie. From archival documentation it was purchased on eeby in '02 and it appears to have had little use since. Don Leslie wrote that sewing machine light oil is a non-harmful substitute to service motors and bearings. I stole a Leslie Junior from a Thomas organ and am building a KUSTOM version Leslie (for the other M-3 I received previously in non-working condition with the main shaft of the TG's bearings frozen). I used high-speed bearing grease on the lower Doppler-shifter lampshade thingee and have had no problems. I think it makes sense to do that when you have it disassembled because the lube is durable and stays where you put it. What do you think of my reasoning on it? chrisinbigbear(california)
It is an amazing story of how Hammond kept rejecting Leslie's speakers as these two together were like peanut butter and jelly and ham and cheese. And still are.
I remember attending an RIT dance with the Rascals playing and wondering "what was spinning in the speaker cabinet?" and now I know thanks for the tutorial.
It was probably 1966 when I went to a teen dance and saw the same thing! All this time, I thought those two horns WERE the speakers! Live and learn... ☺
In those days, any speaker or speaker system using Jensen was top of the line. I saved cash for a long time to replace the woofers in my large stereo speakers with Jensens....and they still pump out AC/DC to Bach, and everything else in-between from an old friend, MC 2100.
I’ve had several 122 Leslie’s...Now I have a 715 that’s huge & has, I think, 4 extra stationary speakers in the mid-section...I gotta’ say, I like what I have better than a 122, but so many models are made it just simply depends on how you want your Hammond to sound...The 122 is “Sweet” though.!.!.!
It doesn't really matter because the sound of this combination is distinctive and iconic ... but ... Less Doppler effect and more interference waves. Either you the listener or the speaker itself has to actually move to create a Doppler effect. The rotating chamber only directs the sound wave coming from the stationary speaker. It also alternately blocks a straight line path from the speaker to your ear. Once the waves leave the speaker cone they can not bunch up or spread out altering their frequency - no Doppler effect. What you hear is the sound waves reflecting around inside the cabinet when the opening to the sound chamber is not pointing directly at you. Some reflections interfere with each other, acting like a subtractive filter, while other waves enhance each other, acting like an additive filter (look up "interference wave"). Since the sound directing duct is rotating the two filtering effects create a vibrato - a "vibrating" volume (not a tremolo or tremulous frequency) effect. The frequency of the tone being produced does not change, but the harmonic structure of the tone does. What you perceive as changing frequency is actually reflected interference waves causing the harmonic overtones to come into and out of the overall sound.
Man! I want so badly one of those! (but probably a 145, 147 or 900 model, with that type of amplifier that comes inside a 145 or 147). But while I can't afford to bring one of those to Brazil (or afford to find and buy one here), I am crafting something similar. I have built a big rotary horn and a small portable low rotor. Next steps are gonna be the small rotary horn and the big low rotor. For the big low rotor, I'll have some work with belt tensioner, balance, torque and speed tuning, which are different related to the horn. The other factors/features can be imported from the same project.
I had always heard that the main purpose of the Leslie, was to break up the "Standing Waves" (not Doppler)that are formed by the acoustics of the walls and ceilings in the room in which it was located. Tremlo was an dded benefit.
+Gerrit Veldhuisen Please elaborate. How is the glasswool applied, on the walls of the box in the middle section, or draped across the 15" driver, or other? Thanks!
Hallo Gerry. Mijn Leslie doet het niet goed. Hij schakelt wel naar snel maar niet meer naar langzaam draaien. Hoe repareer ik dat? Goedkoop natuurlijk...
Dear Jim Huss! I'm making a video on my small channel where I'd like to use a few small snippets of your video to illustrate the Leslie effect. Can I do it?
You can do this as look as you mention how people can find our other videos. Also please send me a copy of your work so I can subscribe to and enjoy your channel. Good luck to you!
Is that the OEM woofer driver? Looks like a modern aftermarket to me. Why didn't they use a Cinch/Jones plug instead of that ancient octal socket? They were around since the 1930's I think.
i had a mint leslie 251 i bought at a used furniture store, they didn't know what it was. cherry wood, hooked it to my a100 hammond with a kit with the two half moon switchs.
You mentioned connecting this to a B3 or C3. Can it also be connected to an A-100? That is what we have, and obviously it has its own internal speakers. Is there a way to do it?
Absolutely! Your A-100 can have a Leslie speaker attached to it, however, a proper kit will need to be installed by a qualified technician to get the best result and then you need to purchase the right model Leslie speaker. There are several ways to go about this and generally we suggest you consult with your local technician to see if he or she understands the parts required etc. We can provide a NEW Leslie 122A and have it delivered directly to your door. Another thought is to consider trading your A-100 in for a B3 with a proper Leslie speaker that you can hear and know in advance what it will sound like. Adding a Leslie to your A-100 has many unknowns. For example, is your A-100 up to its full potential, or does it require an internal restoration to obtain that potential. Then there is the kit installation by a qualified tech and then the purchase of the Leslie speaker. Trying to put all those moving pieces together with an unknown outcome can be frustrating as well as expensive and potentially disappointing. Our company exists to help you eliminate the hassles mentioned and provide you with a great instrument and possibly even a MINT condition Hammond B3 which is what most people want and may have settled for an A-100. Lots to think about! Where are you located by city and state or country if you are outside the USA. More information at: www.keyboardexchange.com
Mainly used for organs but can be interfaced with guitars and other musical instruments via a "combo Preamp" Contact B3buyer@aol.com with pictures if you wish to sell. Then buy what you want with the money. Where are you located by city and state? Leslie speakers have value if you do not need it yourself
Say we have a b3, which has a 5 ping cord, and our Leslie is a 6 ping. The cable cord recently failed. What are those cords called and where can they’ve found. I like playing keyboard but that Hammond, is needed.
The 5 pin connection is at the organ end but the 6 pin connection is at the Leslie end. These cables are called Leslie speaker cables and in your case it is a 5X6. Often a cable can be repaired if you have someone who is handy. Where are you located?
There seems to be an assembly on the right side inside the cabinet which is seen when the back was removed. It looks like black painted wood and is mounted on the right internal wall of the middle section (the area containing the speakers, motors, etc. What is it?
I'm so glad I found you not that you've been lost you've been around a long time I'm interested in purchasing a B3 with Leslie I will be contacting you soon, and thank you!
@@johnbishop5316 the answer should be why not, the Leslie speaker was simply an invention to go with an electric organ, Hammond wanted nothing to do with Leslie and tried to put them out of business. Hammond himself had no musical ability whatsoever, he had already invented 3d films, the electric clock and a few other things and was looking for a product to save his then failing company. So experiments should always be tried, back in the early 60s people were plugging electric guitars into Leslie speaker's, some people were asking why, a few years later Fended made an amp very similar to the original Leslie and Leslie themselves also manufactured one around the same time
This explains why electronic devices emulating a rotary speaker are nothing close to the real thing, whether analog or digital, they just pan the signal left and right or phase shift it, but what about the Doppler effect, and the resonance of the wooden cabinet?
These organ only have 40 watts of power, therefore they don't have alot of power and the overdrive of the tubes cause the organ to distort. The 122 is a great organ however, Hammond made a 222 that has the same internal parts as the 122 but in a fancier cabinet. The JR-20, HR-40 are the first speaker that was created for the sound of the organ however, Hammond made other speaker desined for other organ that can work as well, however the Solid state Leslie give more power and is more accurate.
The 122 sound good but you get more speaker if you get the 710 leslie. The 710 is a rotosonic leslie. It has all the parts of the 122 but an extra speaker for the mid's. You can get the 710 for cheaper then the 122 because most people don't know about them or could not afford them years ago as they are the surround sound speaker of the rotor speaker sound. 710 has a bigger sound and is more reliable because it solid state. The 122A is not as powerful as the 710
The Leslie 21H is much older than the 122 model. A 21H Leslie can and will sound great when properly restored however parts can be challenging to source and finding someone to work on the 21H is also more difficult. The 122 is very much the standard in our modern times. The connection to the organ will be the same for both models so if you have a 21H now, a 122 would use the same connection.
Jim, I noticed on that some Leslie's have a skirt (I always thought it was foam cover with a hole cut out) overtop of the bass drum. Did Leslie's original come with that and does it alter the tone in any way?
***** That's called the scrim cloth cover,what that is used for is to isolate the aerodynamic noise you get from the rotor(wind noise)so that if you were to mic your Leslie you wont have a repetitive wind noise from it on high speed,other nice thing is it keeps the rotor from getting all dusty ,and the Leslie rotor will coast down a little bit longer from the added weight of the cover.the originally came with them the first Leslie 30A and all the others had them expect for the 70s Leslie 122's /147 with the white and the beige Styrofoam rotors
+Sluff Adlin Measurements I have made both with and without the cloth ("scrim") cover show a marked difference in final RPM achieved. With the cover, the example I measured spun at around 270 RPM, without the cover, it was more like 180 RPM. So, it seems that the cover is there to reduce air drag at high speed.
Sparky Marshall Interesting....One thing I have noticed and can hear in a lot of recordings especially from the 70's (and even live some live shows) a "throb" coming from lower rotor (which I find desirable). I'm not sure if that is a miking technique or the way the speaker is set up. Going to assume it's a miking technique but I can't get it from mine when recording, Leslie 251...Hammond A100.
They can sound the same as each other. The main difference is that the 122 can only be used with a Hammond organ while a 147 can be used with many different brands. The motors in a 122 are DC controlled and AC controlled in the 147. Both are great Leslies! Hard to find either. We like to match the 122 and 122a speakers to our B3's (most traditional). The 147 we like to match with our A-100 series organs. Control kits are different so we like to standardize as much as possible. Same wood cabinet, same speakers, similar tube sets...they have much in common but are clearly different in a technical way.
My first question to your question is who is the "they" to which you refer? If you got this information directly from the good people at Hammond Suzuki then follow their suggestions. We do not sell enough of this model to be totally up to speed to be able to give you a correct reply but willing to ask our factory rep the next time we are talking with him. Meanwhile if you have an owners manual that will be a good place to start your research and if and when you figure this out, please let us know so we can all learn together. It would seem logical that moving parts may require some form of lubrication from time to time unless everything is sealed. It will be good for us all to better understand and thank you for your question.....
No. They rotate in opposite directions which is better for balance. Also, only one side of the upper rotor/horn is open. The other side is just for balance and is closed.
On one speed model Leslies, (21H, 44W, 46W, fast/stop), the rotors turned in the same direction. On two speed models (122, 147, fast/ slow) the rotors turn in opposite directions. This is due to the fact that in one speed models, the motor for the lower rotor mounted under the shelf. In two speed models, there was not enough room for the motor stack, so it was mounted above the shelf, inside the middle compartment. Three speed solid state models turned in opposite directions. Horizontal models (or as Leslie called them Decorator models) such as the 222,247, or 351, the rotors turned in the same direction, if memory serves. Balance was not the reason for changing the direction. Most techs will tell you there is no audible difference.
If you have a 1/4 inch output on the organ, you could use a TREK II combo preamp. With the TREK II combo preamp, you use use many different Leslie speakers. I have not seen the Farfisa you mention and I think it to be somewhat rare. It might be a good time to think about getting yourself a restored B3, C3 or A-100 to get the real sound you might want. More information at www.keyboardexchange.com
@@KeyboardExchange Leslie output on my Farfisa looks exactly as your 122 connector (same size) but it's 9 pin. Connector is marked "CBS Leslie". Farfisa has Leslie controls switches ON/OFF , SLOW/FAST.
Saud Cokjat Leslie manufactured a series of Leslie speakers with a 9 pin connection. We recently obtained a model 330 that is in working condition. Other models with 9 pin include 760, 900, 910, 925. There are a few others. I would suggest either the 760 which is the same size as a 122 but with black Tolex covering, or the model 330 recently received. Our 760 is currently hooked up to a Hammond Porta-B so either Leslie could be demonstrated with our Hammond Porta-B. Where are you located?
@@suadcokljat1045 You would need to find a 9 pin Leslie with the proper voltage of 230 volts and 50 hertz if you plan to power the Leslie from your organ if in fact your organ is made for 230 volts and you are NOT using a step-down transformer
Some Leslies were equipped with a reverb system. The reverb played through a 6x9 speaker in the side of the cabinet. That 6x9 is inside that box. That box is to prevent the bass vibrations from interfere with the 6x9. Models equipped with reverb came with an additional amplifier (called the Reverb Amp) that was mounted on the top shelf, next to the horn. The reverb tank would be mounted on the center rear panel. Some cabinets came ready for the additional amp and louvers cut for the 6X9. I do not see the Reverb amp in this Leslie. The reverb system may have been removed (common) or may have never been installed at the factory.
Replace the relay. The relay picks and holds thru a set of points if those fuse then it will stay in the high speed even though you change the selection. The relay will click but not function properly.
Excellent suggestion! Thank you! We are considering adding louvers to the original top back panel to allow sound out but keep fingers and microphones away from the moving parts.
It would be like redlining your car which you rent out to other people who aren't paying for any of the bills to maintain it. If you put it to 10, have someone that pulls out all the drawbars and then floors it, the speakers will burst
The Leslie can be run at full volume, but the system will go into distortion earlier. 7 to 8 seems to be the magic number with distortion starting at the very high end of the organ's volume range.
On my leslie the big thing on the bottom that spins around is squeaking when it slows down to stop. How do I oil this, as it is a cylinder without any openings?
remove the speaker to get to the top bearing you then pull the axel pully asembly up and the rorary wheel slide out the back yoo can oil the bottom bearing there
DO NOT attempt to oil the low rotor bearings. Oil usually makes the bearings worse. I clean and re-grease the bearings. Replacement bearings are available from Hammond parts suppliers, or they can be obtained from a bearing distributor. The bearings are of a standard size and are usually cheaper from a distributor
@@antoniobanks309 Yes, and it's great fun to get at. The main thing to watch is that the drum is held in place by two rubber grommets that are tight on the shaft. They can be extracted. Sometimes they wear loose on the shaft. I had one where some thoughtful soul had superglued them in place so that when I tried to get the drum off, I nearly damaged it. Good luck!
Jim, the Hammond community sure appreciates all you do!

WOW just WOW ive never seen one of those before, thank you for sharing
Lovely explanation. I was looking for something like this and it shed light on more than I expected.
That Leslie sound is amazing when you listen to it in person, nothing compares to real rotating speaker sound when it is live direct from the speaker.
Right. I'm actually here because i'm trying to build a rotary speaker myself (instead of paying thousands of €s for a vintage or modern Leslie)
Good luck with the custom build! I have seen it done.

Adding a Leslie to your A-100 has many unknowns. For example, is your A-100 up to its full potential, or does it require an internal restoration to obtain that potential. Then there is the kit installation by a qualified tech and then the purchase of the Leslie speaker. Trying to put all those moving pieces together with an unknown outcome can be frustrating as well as expensive and potentially disappointing. Our company exists to help you eliminate the hassles mentioned and provide you with a great instrument and possibly even a MINT condition Hammond B3 which is what most people want and may have settled for an A-100. Lots to think about! Where are you located by city and state or country if you are outside the USA. More information at: www.keyboardexchange.com
Great overview.
Thank you for your kind words. This video was made at the suggestion of two of our friends and it seems that they gave excellent advise!
I just found one somebody dumped it . I don't have an organ can it be used for something elce
Mainly used for organs but can be interfaced with guitars and other musical instruments via a "combo Preamp" Contact B3buyer@aol.com with pictures if you wish to sell. Then buy what you want with the money. Where are you located by city and state? Leslie speakers have value if you do not need it yourself
Alright now
Say we have a b3, which has a 5 ping cord, and our Leslie is a 6 ping. The cable cord recently failed. What are those cords called and where can they’ve found. I like playing keyboard but that Hammond, is needed.
The 5 pin connection is at the organ end but the 6 pin connection is at the Leslie end. These cables are called Leslie speaker cables and in your case it is a 5X6. Often a cable can be repaired if you have someone who is handy. Where are you located?
watching this video I realised I need to get a stick
As long as it's wood otherwise you will get a shock
Should have told us which tubes go in there. I would have liked to know
two 12AU7
Two 6550
one OC3
Awesome
There seems to be an assembly on the right side inside the cabinet which is seen when the back was removed. It looks like black painted wood and is mounted on the right internal wall of the middle section (the area containing the speakers, motors, etc. What is it?
it's for reverb which is found on a Leslie 122RV
I'm so glad I found you not that you've been lost you've been around a long time I'm interested in purchasing a B3 with Leslie I will be contacting you soon, and thank you!
Hello Ralph. Please do contact us. Our contact information available on our web site keyboardexchaange.com
Could you hook something like an MP3 player to one of these?
Er, why?
@@johnbishop5316 the answer should be why not, the Leslie speaker was simply an invention to go with an electric organ, Hammond wanted nothing to do with Leslie and tried to put them out of business.
Hammond himself had no musical ability whatsoever, he had already invented 3d films, the electric clock and a few other things and was looking for a product to save his then failing company.
So experiments should always be tried, back in the early 60s people were plugging electric guitars into Leslie speaker's, some people were asking why, a few years later Fended made an amp very similar to the original Leslie and Leslie themselves also manufactured one around the same time
What kind of wood is the 122 made of?
This explains why electronic devices emulating a rotary speaker are nothing close to the real thing,
whether analog or digital, they just pan the signal left and right or phase shift it,
but what about the Doppler effect, and the resonance of the wooden cabinet?
I'm from Nova Scotia Canada, how much are the kits oil, drive belts for a 147 Leslie ??
These organ only have 40 watts of power, therefore they don't have alot of power and the overdrive of the tubes cause the organ to distort. The 122 is a great organ however, Hammond made a 222 that has the same internal parts as the 122 but in a fancier cabinet. The JR-20, HR-40 are the first speaker that was created for the sound of the organ however, Hammond made other speaker desined for other organ that can work as well, however the Solid state Leslie give more power and is more accurate.
if u put a lesslie on a bocanie do u use a leslie cord as an extension cord
how much do they weigh?
How much does a leslie speaker cost?
Отличное видео.Где приобрести такую штуковину ?
The 122 sound good but you get more speaker if you get the 710 leslie. The 710 is a rotosonic leslie. It has all the parts of the 122 but an extra speaker for the mid's. You can get the 710 for cheaper then the 122 because most people don't know about them or could not afford them years ago as they are the surround sound speaker of the rotor speaker sound. 710 has a bigger sound and is more reliable because it solid state. The 122A is not as powerful as the 710
The Rotosonics sound awful. Thery are often blown through ignorant connecting. I got to 45 before I heard one that worked!
Where do I oil my leslie 122 and how? Can I use tonewheel generator oil?
What's with the stick?
How does the Leslie 21-H compare to the 122?
21-H is a single speed unit : off and fast. It also uses a different tube amp than the 122.
The Leslie 21H is much older than the 122 model. A 21H Leslie can and will sound great when properly restored however parts can be challenging to source and finding someone to work on the 21H is also more difficult. The 122 is very much the standard in our modern times. The connection to the organ will be the same for both models so if you have a 21H now, a 122 would use the same connection.
How best to mic this rig?
There are several good videos on UA-cam regarding this subject. Suggest you go to UA-cam for a full tutorial.
Jim, I noticed on that some Leslie's have a skirt (I always thought it was foam cover with a hole cut out) overtop of the bass drum. Did Leslie's original come with that and does it alter the tone in any way?
***** That's called the scrim cloth cover,what that is used for is to isolate the aerodynamic noise you get from the rotor(wind noise)so that if you were to mic your Leslie you wont have a repetitive wind noise from it on high speed,other nice thing is it keeps the rotor from getting all dusty ,and the Leslie rotor will coast down a little bit longer from the added weight of the cover.the originally came with them the first Leslie 30A and all the others had them expect for the 70s Leslie 122's /147 with the white and the beige Styrofoam rotors
+Sluff Adlin Measurements I have made both with and without the cloth ("scrim") cover show a marked difference in final RPM achieved. With the cover, the example I measured spun at around 270 RPM, without the cover, it was more like 180 RPM. So, it seems that the cover is there to reduce air drag at high speed.
Sparky Marshall Interesting....One thing I have noticed and can hear in a lot of recordings especially from the 70's (and even live some live shows) a "throb" coming from lower rotor (which I find desirable). I'm not sure if that is a miking technique or the way the speaker is set up. Going to assume it's a miking technique but I can't get it from mine when recording, Leslie 251...Hammond A100.
What is the difference between the 122 & the 147 ?? Leslie??
They can sound the same as each other. The main difference is that the 122 can only be used with a Hammond organ while a 147 can be used with many different brands. The motors in a 122 are DC controlled and AC controlled in the 147. Both are great Leslies! Hard to find either. We like to match the 122 and 122a speakers to our B3's (most traditional). The 147 we like to match with our A-100 series organs. Control kits are different so we like to standardize as much as possible. Same wood cabinet, same speakers, similar tube sets...they have much in common but are clearly different in a technical way.
on the road with with a122 and a 147...and no one to repair or maintain them...so I had to learn how myself....
Have you ever heard a ventilator vs a 147 out front? Beyond where the doplar effect is near enough and you're hearing it miked up?
Kurt Moss no I haven't Kurt...send me a link if you have one where I can hear it...thanks!
Playback speed to 1.75 for all explanatory sequences.
should I lubricate the 3300 Leslie? they say no, im not sure
My first question to your question is who is the "they" to which you refer? If you got this information directly from the good people at Hammond Suzuki then follow their suggestions. We do not sell enough of this model to be totally up to speed to be able to give you a correct reply but willing to ask our factory rep the next time we are talking with him. Meanwhile if you have an owners manual that will be a good place to start your research and if and when you figure this out, please let us know so we can all learn together. It would seem logical that moving parts may require some form of lubrication from time to time unless everything is sealed. It will be good for us all to better understand and thank you for your question.....
Just want to get clarity on something:
Does the Leslie 247 rotors turn in the same direction?
No. They rotate in opposite directions which is better for balance. Also, only one side of the upper rotor/horn is open. The other side is just for balance and is closed.
On one speed model Leslies, (21H, 44W, 46W, fast/stop), the rotors turned in the same direction.
On two speed models (122, 147, fast/ slow) the rotors turn in opposite directions.
This is due to the fact that in one speed models, the motor for the lower rotor mounted under the shelf. In two speed models, there was not enough room for the motor stack, so it was mounted above the shelf, inside the middle compartment.
Three speed solid state models turned in opposite directions.
Horizontal models (or as Leslie called them Decorator models) such as the 222,247, or 351, the rotors turned in the same direction, if memory serves.
Balance was not the reason for changing the direction. Most techs will tell you there is no audible difference.
My Farfisa Professional 110 has 9 pin CBS Leslie connector. Is there any adapter to connect 122 or must use newer CBS models? Regards!
If you have a 1/4 inch output on the organ, you could use a TREK II combo preamp. With the TREK II combo preamp, you use use many different Leslie speakers. I have not seen the Farfisa you mention and I think it to be somewhat rare. It might be a good time to think about getting yourself a restored B3, C3 or A-100 to get the real sound you might want. More information at www.keyboardexchange.com
@@KeyboardExchange Leslie output on my Farfisa looks exactly as your 122 connector (same size) but it's 9 pin. Connector is marked "CBS Leslie". Farfisa has Leslie controls switches ON/OFF , SLOW/FAST.
Saud Cokjat Leslie manufactured a series of Leslie speakers with a 9 pin connection. We recently obtained a model 330 that is in working condition. Other models with 9 pin include 760, 900, 910, 925. There are a few others. I would suggest either the 760 which is the same size as a 122 but with black Tolex covering, or the model 330 recently received. Our 760 is currently hooked up to a Hammond Porta-B so either Leslie could be demonstrated with our Hammond Porta-B. Where are you located?
@@KeyboardExchange I'm located "in a galaxy far far away" ;-) Croatia
@@suadcokljat1045 You would need to find a 9 pin Leslie with the proper voltage of 230 volts and 50 hertz if you plan to power the Leslie from your organ if in fact your organ is made for 230 volts and you are NOT using a step-down transformer
What is the purpose of the little box in the middle compartment to the right?
Some Leslies were equipped with a reverb system. The reverb played through a 6x9 speaker in the side of the cabinet.
That 6x9 is inside that box. That box is to prevent the bass vibrations from interfere with the 6x9.
Models equipped with reverb came with an additional amplifier (called the Reverb Amp) that was mounted on the top shelf, next to the horn. The reverb tank would be mounted on the center rear panel.
Some cabinets came ready for the additional amp and louvers cut for the 6X9.
I do not see the Reverb amp in this Leslie. The reverb system may have been removed (common) or may have never been installed at the factory.
@@scottbc31h22 thanks for the answer
@@LegitTheProducerBackup You're Welcome.
my 122 stays in the fast or slow mode unless I rock the cabinet physically. how to fix? Thanks Rich
+Richard La Bossiere
Sounds like a bad relay mechanical relay. Replace with solid state relay from Tonewheelgeneral.
I have a 251 Leslie but it’s recently been stuck on fast. I can hear the relay click when I change speeds so what could be the problem?
Replace the relay. The relay picks and holds thru a set of points if those fuse then it will stay in the high speed even though
you change the selection. The relay will click but not function properly.
Use mesh plate if afraid of hurting anyone's fingers/hands/extremities
Excellent suggestion! Thank you! We are considering adding louvers to the original top back panel to allow sound out but keep fingers and microphones away from the moving parts.
why shouldn't there organ Leslie volume exceed 7 and 1/2? Shouldn't you almost to fit your church or home needed volume?
It would be like redlining your car which you rent out to other people who aren't paying for any of the bills to maintain it. If you put it to 10, have someone that pulls out all the drawbars and then floors it, the speakers will burst
The Leslie can be run at full volume, but the system will go into distortion earlier. 7 to 8 seems to be the magic number with distortion starting at the very high end of the organ's volume range.
On my leslie the big thing on the bottom that spins around is squeaking when it slows down to stop. How do I oil this, as it is a cylinder without any openings?
remove the speaker to get to the top bearing you then pull the axel pully asembly up and the rorary wheel slide out the back yoo can oil the bottom bearing there
DO NOT attempt to oil the low rotor bearings. Oil usually makes the bearings worse.
I clean and re-grease the bearings.
Replacement bearings are available from Hammond parts suppliers,
or
they can be obtained from a bearing distributor.
The bearings are of a standard size and are usually cheaper from a distributor
I have a leslie 122 and the bottom rotor goes slow/fast, but the top only goes off/fast. Can anybody help me?
I can take the top off, I do live in a chamber.
Ill buy my leslie from him i use an iorio accorgan midi syntara accordion
Great but how about some wholly bully
5 pin or 6 pin .I still have my cables!
What to do when the lower rotor stop spinning Mr. Russ
Replace the belt (looks like cord.) Or if you're lucky, it has just stretched or come off. Just put it back on and retension.
I didn't know the bass lower rotor had a belt I thought the upper lower only had a belt
@@antoniobanks309 Yes, and it's great fun to get at. The main thing to watch is that the drum is held in place by two rubber grommets that are tight on the shaft. They can be extracted. Sometimes they wear loose on the shaft. I had one where some thoughtful soul had superglued them in place so that when I tried to get the drum off, I nearly damaged it. Good luck!
Thanks @Mr. John Bishop I really appreciate it
