Re: Leslie 700

1) The 700 is indeed 2 channel. Rotary is handled entirely by the 6x9" Rotosonic drum. Stationary by the 15" and the 2 2x9".

2) As is stands it's not compatible with the H. The channelling is all wrong. You're going to have to somehow build a kit for it that mixes the two main channels of the H and then filters off the bass to the straight channel of the leslie to divert it to the 15" speaker. (this crossover has been discussed before on here and Hammond Zone).

3) You can get schematics for the H (I think someone posted them on here). 700 schematics are here:- http://www.captain-foldback.com/Leslie_sub/Leslie_schematics/700.GIF

I think you may be in for a tough job mixing everything the way you want. Worth posting on Hammond Zone to see if anyone's done this before, and perhaps checking out the kit schematics for the 8216 and 8240 - both on this page:- http://www.fishorgans.com/leslie_kits/ to see if any of it makes sense to you.

Re: Leslie 700

Hi ANd thanks JJMcS and Andy!!! 

Please help!....


It came over today... Want to test the rotor... ; IS IT pin seven to grnd for slow? .. It so states on one of the sites... should I try it...?

It has been altered.... ; It has three female connections, one stereo 1/4 and two rca... Each rca goes to one channel... one to the bass/upper 6X9's the other to the rotosonic connection... so those ARE the two channels, I assume.... ? There WAS no cable..., when it was purchased by the owner from whom I purchased..., .. He told me.., It cane from a nightclub and was used for several inputs inc hand held mike... All that was offered was the cabinet... 

The stereo goes through a couple of other components as well and then to the other sides of the two channels.. it appears.... 

In addition the cabinet has been wired 117V..anew.. a few years ago from the looks of the line chord..., for 3 line W/ground (gr) which IS attached.... is that normal for this unit? the amp works fine to my finger nearness to the inputs....... I haven't tried to input anything yet... all is very quiet, 

Please comment on what I have found and your view of the added inputs , if you care to!!



Many Thanks!! John

Re: Leslie 700

Those added input connectors will probably make your job easier. The ac cord sounds OK to me. I have a similar ss amp that way. Grounding pin 7 is correct. It looks like you got the 700 from Ft. Walton that was on ebay although the ad said it came from a church instead of nightclub. Good capture.

Re: Leslie 700

Interesting to read the input details on your Leslie!! Connector jacks would be non standard I think.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p>

I’ve a few a comments in response to your questions: <o:p></o:p>
<o:p></o:p>
“In addition the cabinet has been wired 117V..anew.. a few years ago from the looks of the line chord..., for 3 line W/ground (gr) which IS attached.... is that normal for this unit?”<o:p></o:p>[/I]
<o:p></o:p>[/I]
No, the power connection would have been made through the Leslie cable. 11 pin cabinets have a power cord. I would agree the power cord on yours would be okay.<o:p></o:p>
<o:p></o:p>
<o:p></o:p>
“It has three female connections, one stereo 1/4 and two rca... Each rca goes to one channel... one to the bass/upper 6X9's the other to the rotosonic connection... so those ARE the two channels, I assume.... ?”<o:p></o:p>[/I]
<o:p></o:p>[/I]
Yes seems so as per your suggestion.<o:p></o:p>
- RCA jacks would be for input to the stationary channel.<o:p></o:p>
-1/4" jack input for the rotary channel.<o:p></o:p>
<o:p></o:p>
“The stereo goes through a couple of other components as well and then to the other sides of the two channels.. it appears...”.<o:p></o:p>[/I]
<o:p></o:p>
I’d suggest watching the inputto the 1/4' phone jack as there may be a preamp behind itthatwould support the microphone. Hopefully one of the components would be a crossover to keep the bass output out of the Rotosonic speaker and channel it to the stationary channel.<o:p></o:p>
<o:p></o:p>
I realize you are only interested in the slow speed only but it would be interesting to know what the provision is on your Leslie for speed control. <o:p></o:p>

Re: Leslie 700

Hello!! Keith and Admiral..!!.., and others


Indeed, I was really hoping to have gotten away with something that might be reasonable... , and after pulling the amp for cleaning....; there are no connections any longer to the nine pin plug; cut off against the plastic, when I got in to it.....!


Cleaned, and reassembled...got it all I believe... and hope I didn't mess up any circuit.... Signals in go in all three jacks o.k..... sound fine....

\BUT..., my rotosonic won't turn...(?) It sits and hums some..., I have lubed it up sparingly ..., it goes for, like a sec. (no more! ), and then quits... before doing it again... Coils on small motor heat up slowly , not burning, ... BUT..., it seems too much heat to me... I cannot tell from what I was looking at, under the chassis , what the change-artist... had rigged for the speed... , so I don't know what is going on... but...I SWEAR it seems to me both motors are trying to run....(?-?) CAN... I hook direct to 117 with these motors instead of through the amp... to see what it does?-? 

Thanks again to all!! John (ellll)

**Guest** · 09-27-2009, 09:54 AM

Re: Leslie 700

Uh...Oh..,

Went and looked at the schematic ... and there are diodes..transistors, and relays etc..all through that motor-run circuit... so I just may have a hook-up problem for sure...(?-?).. unless I can just hook the slow direct...(It is ALL I want... I played my share of tremolo years ago... I want Sunday Church in my living room now....)

Any comments in the run cycles that night be wrong here? and again, CAN I just hook to the 117 volt supply....?

Best Regards!! John

Re: Leslie 700

Yes, you can hook the motors up directly to ac. You may have both motors trying to engage at the same time. That would be a possible cause of the problem you mention. Unfortunately the motors plug to the amp with a plastic plug and all connectors inside whereas the older Leslies simply use ac wall plugs separately. You can cut the two wires going to the slow motor and put an ac plug on it or wire it directly to the amp ac so when the amp comes on it will also. You won't have any control over the motor speed that way but I think all you want is chorale anyway. This would do it. Actually not having to use the 9 pin connector may make it easier for you. I have a similar 825 amp hooked up without the 9 pin. Works great.

Re: Leslie 700

Hy Admiral !!,

Havn't forgotten you or your offer to help you gave before...! You might enjoy a VERY short horror story of getting the cab... When we found we would have to pick up.., we took off with a big OLD sedan instead of new Honda Civic...(back seat out..) and went "beach" from Panama City to FT Walton Beach... on a big tourist time here at season's end.., on the one hand .., and Thunder beach on the other..., and it was Baaaadddd... all the way... Needless to say, we came back with the Leslie.... all the way on 20.... MUCH better traveling... (Heaven knows why I went front.... I do know better... but thought the traffic might be light...)

Anyway, I thank you for the timely advice, and I will use the method for a starter.... The "modifier" pit a double throw switch... (maybe it was all he had...) and there are two poles waiting for a hook-up .. If I change my mind.. just go in and plug it the old way and switch the other way on the switch... Perfect...!

Thanks for the great advice!!! John (ellll)

Re: Leslie 700

Hello friends,



Everything works fine, and I did briefly hook the other channel to the second contacts on the switch... without the leslie 117 volt plug in... just the amp...It was fine as well so it would be easy enought to do that at the console and have a good enough change pattern if you were not using a lot of tremolo alt with chorale... so I am quite haqppy with it

HOWEVER... I would like to have the feed for the motors and the amp. all together as intended, as this IS a Leslie, even if the 700, decorator model, so I will work on that a bit more. It must have a bad component or is mis-wired, as everything works fine, each alone ...

I will mention it is a near perfect cabinet, and only needs a touch or two with filler, and a compounding and it will look almost like new... Also still planning to build simple units from old organ removal foam drums..... 

I didn't realize this 700 model has a heavy wooden drum and is very well set, balanced and insulated... it is absolutely silent when running...; (JUST the motor on slow and the drum... NO amplifier...) If you place an ear right up to the cabinet, when completely closed and the screws tight... you will NOT hear the drum and motor when you switch it on.. promise... not even at the sound ports at the bottom, all you hear is the air change when the drum port passes... If I can keep the amp quiet, all will be fine..

So.. thanks for the help... It will suit me for a while, and I will work towards better! 

My Regards to you! John (ellll)
