M-111 line out

[Nicholas]

I found this diagram for wiring a line out to a Hammond spinet organ.

I'm not great at reading circuit diagrams, so I'll tell you what I'm trying to do and hopefully someone who knows more about electronics than I do will be able to tell me if I need to modify the circuit, and if so how to modify the circuit.
I have used guitar amps that switch off the internal speakers when you plug a cable into the extension speaker jack, and I would like to have my line out work the same way. I know that I need a load on the amp to replace the speaker resistance, so ideally I want a circuit that takes the "dummy load" out of the signal path when there isn't a cable plugged into the line out and puts it in while muting the internal speakers when there is a cable plugged in. Would the circuit above do that or would it have to be modified?

I posted a similar question on a forum. A Leslie Main/Ensemble/Echo switch will allow you to switch between the output, internal speaker and both.
I just installed the trek II line out on my M-3 and actually enjoyed having the extra umph from the built in speaker at the gig I played with it friday. It kind of acted as a monitor for me because my rotary speaker was across the stage behind the guitarist. Not an issue for everyone but I enjoyed it plus those switches aren't cheap. I like your idea with it only being active when the cable is plugged in. I would like to see what answers you get.

May use this original below with some imagination or as it is. It did the job for me on few spinets.


Or this one

The problem with those two schematics is that they don't tie in the reverb channel which has to be specially mixed on the M100. I posted about this yesterday.

[Nicholas]

I don't really want the reverb channel included in the direct out. I'd rather just have the main signal and have it be as simple to use as possible.

If you are planning to use this organ in a live performance environment, I would encourage you to re-think that decision. I find organ-switchable reverb to be *very* useful.

[Nicholas]

My organ is only used for recording and I used to just mic it, but I just got a modified Leslie cabinet that takes a speaker level quarter inch input for audio. So I plan on using the Leslie for the main signal, and micing the reverb speaker separately. I really am no good at reading circuit diagrams, so any recommendations of which of the schematics blhristov posted would work best for me?

[Wes]

If this was my setup, I would figure out how to hook the organ to the Leslie at the factory-designed audio levels!

Can you document what modifications have been done? It's entirely possible that the quarter-inch input is designed for speaker-level inputs anyhow. That's how I built out a Leslie 25 last year; he plugs the ext speaker jack from a guitar combo amp into the quarter in.

If the Leslie has not had an extra amplifier grafted into it, chances are about 95% that it was made for speaker-level inputs. I would expect the extra amplifier to be very, very obvious upon inspection.

Yes the Leslie line in is speaker level.

Can anyone dumb down the circuit diagrams blhristov posted above? I'm not going to lie and pretend I understand them.
