  1. Christian from Graz, Austria - what a wealth of info and repair hints! Thank you all so much!!

January 2016

  1. Jon and Kim from North Bay, California. This site is a great find. Just happened to have an A-100 handed to us today. Super excited. So far the Tone Generator seems to be pretty gummed up. Hopefully, with a little oil and some elbow cleaning grease, we will be up and running soon. Leslie will be next. I have searched for tips on repairs, cleaning, etc. and I keep bumping into this wiki. Awesome.

(I've re-organized this page. Now it's reverse sorted by month. If today's month is not listed, add it at the top of the list. -- JeffDairiki)

  1. Hi! Michel from Longueuil (Quebec). I own a 1963 A-122 with a Leslie. I try to practice every day!

December 2013

  1. Great idea to make this site a wiki so that anyone can contribute. I have just stumbled upon a project, a Leslie 760 that need some caring. I found the information here really useful. Anders Lundkvist, Piteå, Sweden.

  1. Just found this awesome wiki. I played a portable Gibson/Lowery organ back in the 60's and 70,s, but quit when I went to college (Big Mistake!). Now I am semi-retired so I bought the Hammond I always wanted...well almost. Instead of a B3, I bought a XK-3c with the XK-L and full pedal board, due to portability. I also have the Leslie 3300 to play through. Have been trying to figure the keyboard technology out for 2 years and progress is very slow. The manual is not very clear, nor is the instrument real intuitive. Also, there is no one in my geographical area to teach anything organ-related, technique or technology. That is why I am glad to find this wiki. While I am sure it will not make my left hand move well independently of my right, there seem to be some great information here. thanks to Jeff Dairiki and all contributors. -- Jeff Junck ( 11/11/2012 Mountain Home, Arkansas.

June 2012

  1. Awesome find this wiki. I just acquired a 'free' A102 that's been sitting for over two decades and she needs a lot of love right now... This site will certainly make the journey less perilous. Many, many thanks... -- Todd Wilson (portland or)

  1. This will be a valuable resource for my first attempt at restoring a C-2. No Leslie, though :-( -- Rich Gabrielson

February 2012

  1. Thank you so much for all invaluable help here! Let's see, so far I've fixed a 60-cycle hum and percussion issues on my '59 B3 with what I've found here. I'm also planning on hooking up a main/ensemble switch running a tone cabinet and 145. Thank you, thank you!! — ?DavidStarchman

    BTW, for those looking for percussion issues, unsolder the white wire already and measure the resistance!

October 2004

  1. Hey! Thanks for this cool site for info. I bought a 1958 M3 off e-bay. Perfect condition. Well maintained organ from a defunct church. It was in a small town church for 46 years. I am looking to add a effects loop. To try various tone cabinet modelers and modulators out there...(POD, ?RotoVibe, Uni-Vibe) I play guitar in a band and dabble in keys. Any help from various people here to help me figure out a effects loop for the Ao-29-G EM speaker amplifier would be appreciated. Add a note here or leave message at yahoo groups hammondzone.

September 2004

  1. Wow! I can't be first but I can be next! This is a great place. I bought a 1955 M3 a couple of weeks ago (cheap!) just becase I've always wanted a Hammond. That sound! Being a tinker at heart I built the line out box that's posted here and it works great. You should hear a little "M" just slightly overdriving a 1964 Fender Twin reverb Amp loaded with JBL E120s! I plan to add foldback to the upper manual (just won the pieces on ebay) and clean out the "growth" (rebuild) in the vibro scanner. All of these "organ" terms I didn't even know existed a couple of weeks ago. Because of your excellent site I can do all of this myself. Thanks very much for the education. NEXT STEP, Leslie and a console model! Lubricate your organ! I laughed the first time I read that!

  1. Ben Patron/Cherie Woodward - Cool, CA: Back again. The TG is spinning freely. Thanks again to the great content found in the fab HammondWiki. Now looking for the in-depth in the synch motor.

  1. Tony ( Interesting site.
  2. Ivan Georgiev ( I am just curious about Hammonds.
  3. Greetings from New Jersey - ThomasLaresch. I added a page about ChordOrgans.
  4. Ben Patron/Cherie Woodward - Cool, CA: Just bought a fine A-102 at a garage sale. The Tone Generator was gummed up. With a little luck and your fine page on the TG, we'll have our organ up and running in just a bit - and now we won't use BraKleen on it to un-gum it! Fantastic info -- thanks, Jeff!

January 2003

  1. Jocelyn 'Joce' from Montréal: Nice website, I did the bypass for the percussion improvement on my A100. The organ sound better, more 'growl'. A Gift for all of us, try this amazing 'jazzy fat vintage B3 sound': 866222227, C3 On-Off, perc: ON, NORMAL, FAST, THIRD & SECOND ALTERNATED IF YOU WANT (with internal modification of perc. explained on this site) Nice sound. Great bass line on the swell !

  1. Dennis Dyer ( ) stopped by here, this is good site.... I'm running a 1963 Hammond A-102 and a 1974 Leslie251 in my recording studio...... reliving my old rock band days from the 60s and early 70s (anybody remember the Wild Cherries?) I modified a 6147 connector kit to use on the 251 and still maintain the reverb from the Hammond. I also have a excellent Leslie model 47 sitting here trying to decide what to do with it, maybe find a combo pre-amp for it.
  2. Alex Sachetti was here...
