    So I have an old Hammond organ, nothing fancy but I love how it sounds. Anyways recently I noticed it has an output tucked away on it, all it says is 120 volts 60 hertz 2 amps. I can't find any info on this particular organ online.

    So would it be most likely a speaker out I should only use with a cab? I haven't opened it up yet but I assume it has some sort of amp built inside, maybe a tube amp as it's from the 70's.

    I have mic'd it before and it sounds amazing, it needs some repairs but it sounds great. Sadly the bass floor pedals often don't work, I need to check the wiring in the back soon...

    Anyways should I avoid plugging it into anything? I have a cheap old guitar amp I could test it on.

    How about you post the model of the organ?
     
  4. That description does not sound like a speaker output.
    Rather it sounds more like some kind of power output to run an auxiliary device.

    Maybe a Leslie speaker cabinet?
     
  6. Could be. Probably powers the motor?

    We had one of the 1960's Hammond B3's for many years and as I recall the Leslie (a 122 I think) and PR-40 cabs hooked up with thick multi-pin connector kind of cables. I think that's where they got their power, but it was a long time ago so I may be wrong.

    Post your question to organforum.com in the Hammond Organ forum. Many techs are regulars.

    The label 120 volts 60 hertz 2 amps is AC power related. I've had organs with daisy chained speaker connectors. Some organs have a preamp out, some have a preamp in that allows you to run an instrument through the organ amp and speakers. Features depend on the organ.

    But sure, an organ into a bass amp works well.

    Back in the day, A buddy of mine did the wiring on my Hammond M3 so I could run the bass output to an amp(Ampeg model? head w/2 vertically mounted JBL D130s in a cab) and the treble/power to the Leslie horns, which I had removed from a Leslie Tallboy(6 foot tall, huge bass box with a twirling cloth covered contraption with little usable output for miking) mounted into a separate DIY black painted box for easier transport.

    I set the horn box on top of the speaker box and the Ampeg head on its side on the floor. The box did not have a top on it to make room The twirling horns. Possibly a little Odd looking but very effective setup.

    I also used the 2nd channel of the Ampeg for a Fender Rhodes. Nice sounding rig.

    +1 to checking out the organ forum to find a wiring diagram for the Hammond multipin plug.

    Just to be clear, that is not an audio output.

    my Hammonds had an output that went to the preamp pedal ... then to the Leslie ( powered spkr ) ..

    not sure what outputs are on more Home models with built in amps/speakers ..??

    Post the model number here, or a picture. I can help identify it. If it's an M3, wiring a 1/4" output is easy. For a B3 or C3 it's a little more complex. I can get you diagrams for either.

    I will keep collecting until I have 40 basses

    Keith Emerson ran a Hammond into a marshall

    I think you're thinking of Jon Lord.

    I have a Hammond M100 that I connect to a guitar amp from a RCA cable jack that is on the side of the volume pedal box.

    Never put your organ into anything that even remotely looks like its meant for electricity

    Leslie to Hammond connections are indeed more complex then just a 1/4 inch plug. They are often 6,9 or 11 pin cables that also supply the speaker amp power.
