Originally posted by Kayaker-J I hope that doesn't apply to a Hammond A-100 with big Leslie. I haven't fired these up since I took over the old homestead, because I know that would be a bad idea until they are properly lubricated and serviced. I have no idea where I'd find someone locally who really knows what he's doing with respect to servicing these venerable, still uniquely compelling antiques. Maybe find a jazz band still schlepping a real Hammond B-3 around...
There are any number of sites on eBay that carry Hammond Generator Oil. I have never owned a Leslie, so I don't know what the oil is for the bearings. Once you take the back cover off the Hammond, the lube points are easily located on the generator. It's been 45 years since I had anything to do with them, so I cannot give you an oil drop count, but I am sure you can find that on the web as well.
You are very smart not to try to fire the old girl up until you have lubed it. Many a generator has died with bad bearings from lack of service. Even if you lube it after it has been used for several years without servicing it, often you find transients from the shaft motion in the bearings are contaminating the sound.
PS: If you have never used an older Hammond, it is 8 seconds on the start switch before you turn on the run switch. Then I usually held for an additional 8 seconds or so, making sure it settled into the run speed. You can hear the start coil whining after you hit the run switch, and it should be stable before you let go of the start switch.
PPS: Use a vacuum cleaner and get all the dust off the electronics in the back. Some dust bunnies are flammable.
