Anybody Know where I can get a schematic for a Hammond M3 organ? I'm trying to get this organ going again.Any help would be appreciated.

Awesome site!Great schematics.
Hopefully with these I can make this M3 bring
back a nostalgic sound that is real,not digital
reproduction into my studio.
I've an M3 that sat long enough to allow the the lubricating oil for the tone wheel to dry up. I can turn it by hand, but it requires great effort. Anyone have a tip to loosen it up without tearing it apart? I've tried adding oil to the oil ducts, hoping it would wick in there and free things up, but it seems to be very stubborn.
Did you use Hammond oil? Anything thicker is gonna get you in some trouble.
I've know of a few Hammonds that were similarly dry, but by twice filling the cups with Hammond oil and letting them drain into the tone generator, things freed up. They all run great to this day (including my own M3).
Sometimes great sound is simply the result of an honest mistake.
Welcome to Tech Talk!
I just checked out your site- Wow! what a cool project! (RCA BC-3C valve mixers)
How are you doing with them? You never know, you may find someone here with information and/or schematics for them ;)
...I wonder if any of the bits in your mixers are here at Waltzing Bear ?
Hey Mark, That place whew I used to work near you (you know the name!) has a couple of diffrent Leslies... I was stunned when Peter Coghlan showed me the "Mercotac" from one of them... -Besically it's a pair of dual-concentric Mercury pools, with fixed contacts coming out of the bottom, and moving contacts coming out of the top... The ultimate low-noise rotary speaker sliding contacts!!! (used to feed the rotating midrange speaker in some models )
-Spares are a bugger to get hold of though ;)
The old believe everything; the middle aged suspect everything, and the young know everything.
Wow! A health+safety issue ready to explode methinks!
...which reminds me of that experiment at school where they demonstrate an elementary "motor" by passing a current through a wire dipped in mercury held in a magnetic field. It moves quite spookily- must've been a great "gag" at those Victorian after-dinner "science demonstrations"!
