Repairing a Hammond 8022m with a Leslie speaker

Hi everyone,

The other day my friends and I spotted this Hammond/Leslie combo on the curb not far from my home. I decided there was no way we could pass this up and they helped me carry it back. It's very dusty and in dire need of repair and refurbishment.

This is going to be my summer project, but I have zero idea what I'm doing. That's why I came here! I have enough experience with electronics and woodworking to repair it, but I know absolutely nothing about Hammonds.

Anyone who can help me figure out what I need to do will be my hero. The ID card underneath the keyboard says it's an “8022m” and there is a Leslie speaker attached.

Questions:
1. What parts are most likely to need replacing and where in the organ can I find them?
2. What parts/aspects of the instrument should I be aware of in general?
3. Am I going to need a special tool?
4. How does this draw power? Do I need a plug or is there an internal power source?
5. Am I in over my head here? How much could this cost me?
6. How much should it sell for fully refurbished and working?

Let me reiterate: I don't know anything about this instrument. Please define vocabulary for me (I.e. I've heard Tone Wheel a lot and idk what that is)

Welcome to the Forum, jmkc. However you may not like the facts that I'm about to give you!

1) that's a very old (1974) Hammond Cougar and the Leslie unit is built in. An 'attached' Leslie would be a large separate speaker cabinet plugged into the white 9-pin socket in the photo.
2) No tonewheels, it's a first generation LSI Hammond. (Large Scale Integrated circuits). Not particularly reliable.
3) If you're asking question 4 then the answer to the first part of question 5 is quite probably 'Yes'. You do need to plug it in! It looks like the mains lead has been deliberately ripped off or removed. Most likely because the organ doesn't work.
4) the only way to get any parts is to have another identical donor organ.
5) If you spent a lot of time, effort and money on it and got it fully working, the eventual selling price would be roughly zero, maybe $5-10 - IF you can find a buyer. Better, bigger and newer organs are out there for free or for pennies.

So, I'm sorry, but it looks like your summer project is off and you'll need your friends again, to put it back on the kerb. Now there are some good Hammond organs out there that would be worth restoring. A proper tonewheel Hammond like an M100, L100 or a T series model, for example. But the important word is 'tonewheel'. That refers to the electromagnetic tone generator system that Hammond invented in 1933 and used from 1935 to 1974 in many of its organs. You'll find plenty of info here on the forum about such modelss

Dump this one, look around and tell us what you can find, we'll guide you!
