I am going to see if the extra taps on the OT will let me use an eight ohm speaker. If so I am thinking of the following circuit.
I need to replace a number of components, add some others, might just be easier to start from scratch. We will see. The reverb is from a Blues Jr, never built it so it is a new experience. I am guessing the voltage will be low so might go SS rectifier.
Hammond L-112 Organ.
You know, going from the 130-150 lb Yamaha's to a 220 lb Hammond, you really feel the extra 70 lbs. Mind you it is 50% more weight. And normally I don't bother with them if they need to go up stairs. If I would have known I would have passed it by. I am now looking at the manual and I see it has the bass and treble speaker pair. From what I recall they both sound like crap for guitar. Darn, live and learn.
I just noticed your age. IHehe... I feel soooo much better after reading this thread! I thought I was bad but you (might) have me beat!
Maybe not. My back hurts today. And I will probably just leave it as is and it will take up space in my garage. I wish it were half trashed, it would be apart in a day. I still am considering something along the lines as you had done. Make it functional but without the weight and volume. But I have many things to do first. No shortage of parts.Great score!!!
Personally, I won't part out a tone wheel Hammond unless it won't work. They are real musical instruments, unlike the vast majority of electronic organs.I am assuming it does.

I've sold a few of them that I picked up free. You can always get 100-150 bucks for them. They typically just need oil because people run them dry. Use mineral oil if you don't have Hammond oil. It takes up to a week for the oil to soak in.
I thought about chopping my last one, and using the amps and speakers for guitars, but other projects got in the way. I may do one someday, but I see fewer organs on Craigslist every year.Not a lot of people around here interested in an old organ. The only ones are the guys wanting to sell the guts for guitar amps. I was hesitant to get it but decided to shoot first and ask questions later. Talking with the guy it seemed he had no other callers. We are kind of an island with now other major population center within a 5-7 hour drive.
The tube of oil is sitting inside the cabinet and looks mostly full.
I did the foldback mod to the upper register of my M100. It was a somewhat tedious operation, but fun, and really brought the thing to life. You can also foldback the footpedal bass to the lower register I think.I just watched a few videos of modifications that can be done to the organ, I do not think this one will be going away soon. Might be a year or three before I get to it but I think there are some good times here.
Hey Bender,Don’t need all that heavy iron adding weight unnecessarily. It’s not adding much to the tone at this point and the iron could be put to a better use. If you could point me to some info on how to do this I would appreciate it very much.
Are you asking what to do with the Hammond Amps?
Oh, now I get it.oh…I know what to do with the iron… I just don’t want the chopped organ to weigh any more than absolutely necessary.
I recently purchased a Yamaha Reface YP organ. I’m picking up a few tunes in my working band that I will be hopping over to play keys on. It does awesome Hammond tones and the on-board Leslie simulator is very convincing also. But, I have another band where we put on bigger production/flashy shows and you just can’t beat a big ol’ Hammond and Leslie up on the stage. Our last show we did with that group, right before the ‘Rona hit, we even had a 9’ concert grand piano up there!
Not only the amp, the organ cabinet around the speaker. If I wanted to make a light weight unit most of the organ cabinetry would go as well as the bass pedals. Use a 12V laptop power supply, a high voltage switching supply to feed the tubes. A Class D power amp.Oh, now I get it.
The problem is that Hammond organs typically use the B+ for stuff like Vibrato and Percussion circuits.
I guess you could clip the amp out so you could carry it separately, for portability. But obviously, you'd have to wire in jacks and plugs and put the amp in its own cabinet. Probably more trouble than it is worth? The amp only weighs about twenty pounds.
