I also have an X 77 GT,and somewhere in all these files I found someone who cleaned the push on wires that go from one circuit board to another and so on.I took their advice and today cleaned mine,( at least the ones I can see).The results are outstanding.My organ now sounds like a Hammond.I am thrilled. Note before unplugging anything I took a lot of pictures of the boards first,and it was good I did.Now I along with others am waiting for the repair Manuel,or CD,If there is cost please email me for a fast check.Thank the forum.It is wonderful.Donald Roberts Katy Texas
I tried your posted email address,but it did not work.Habe I done something wrong ?I would like a PDF file for the X 77 if you will help me.I have an X77 gt model.Thank you very much

Just boughtan X77GTwith the matching X77Pleslie(amazing organ). Thanks Tim, Robert and Andy for help so far. Happy to be here. Now I start looking for a manual and ways to upgrade my baby. I am not hearing many of the problems others are having with there X77's, only a bit noisy so far. They may have fixedsome of the problems with the GT model.As i skimmed the previous notes, I think there is a good group of people here and look forward to joiningefforts and sharing whatI find out with all of you.</P>
I told a friend of mine (ok maybe "friend" is stretching it a bit)LOL that I had just bought an X77GT and his reply was "Not bad for a transistor based organ".I just love wannabe purists. Imay have to remind him that I just sold him an A100 and a C3</P>
Now to look for a"Push on wire". Justhave to goin there withoutknowing what I'm doing. Who knows, I may have a shocking experience Don</P>
[quote user="ImaJical"]... with some modification, can ACTUALLY OUT PERFORM THe IMMORTAL B3!!!!
Points to consider:
-This instrument looks Gorgeous (Funky...not like a church organ) in your living room.
-X77 contains MODERN electronic components, so re-capping etc is not required.
-X77 is ALL solid state, so electronic parts are easy to get.
-X77L leslie tone cabinet is a 200 watt 4 channel beast!
-No "Gooey Foam Problem" like many of the 60's Hammonds had.
-Console comes appart easilly, and the many circuit boards are easy to get at.
-X77 has the funky B3 percussion built in...but needs an adjustment to tighten it up.
-ALL HUMM and FIREWORKS problems can be TOTALLY ELLIMINATED!
-Learn how to ADD the ORIGIONAL Hammond B3 vibrato scanner (C3 chorus) to the X77.
-Learn how to mofify leslie X77L to function like model 122 on steroids!
Should there be enough interest in this I will provide a website with MP3s to demonstrate EXACTLY how EXCITING this instrument can be
Sincerely

Hi Don,</p>
Well I've taken the plunge and now have a X77 wth X77L sitting in my living room next to my suitcase Rhodes ( and my wife standing across the room with that 'new gear in my living room' look in her eye... man I love that woman! ). I am very interested in the mods you describe in your post. Especially the adjustments for the percussion and the mods for the X77L. Also if you ( or anyone else ) has any suggestions/diagrams/etc on adding a switch to shut off the vib/treble horn to get the 'ramp up/down' sound it would be GREATLY APPRECIATED ( hopefully some details as I am a 'player' not a 'tech').
</p>
Thanks in advance and <span style="font-weight: bold; font-style: italic;">HI Y'ALL</span> to everyone here in the forum ( "newby who just signed up says 'what'"... "what?") </p>
Hi Dan, welcome to the bunch. There was recently a discussion on bypassing the horn here. It basically involves putting a 4-pole, double-throw switch after your amp's output. With the switch in one position, everything is as normal. With the switch in the other position. the amp's output completely bypasses the crossover (which where the sound 800hz and above gets peeled off to be sent to the horns) and sends the full output to the lower rotor only.</p>
If you are just wanting to hear ramp up, it seems like you should be getting some of that anyway. The horns and bass rotor change up/down at differing speeds, because they are not synchronized, and the horns are much lighter than the rotor.</p>
thx-Scott S.

Hey Scott! Great to be in the company of so many Hammondologists! I was hoping to find some kind of cutoff of power to the horn so that I could control the spin down...spin up sound. Not quite the same as toggling the Celeste and Vib on/off. I am also wondering if there might be something wrong with the bass rotor... When I kick on the Celeste I can hear the 'Chorus' effect for a moment but it shuts down ( spins down maybe) and then I can only hear a more 'straight uneffected' sound.</p>
I'm not familiar with your Leslie, is it a two-speed, one-speed or just "on"? You can safely insert a switch to kill power to any of the motors if you want.</p>
thx-Scott S.

Hi..my name is Tim and I am an X-77 junkie...OK, that's out of the way..the leslieswitching on the X-77 seem to be timed so that you DON'T hear the horn ramp up or down, on purpose? The roto sonic drum is on fast all the time. I've gone through every single nook and cranny of mine, and I am pretty surethe only thing I still have wrong is 2 notes won't sustain in the "harp" mode. Pretty good for just exercising and de-oxiting contacts and pots.</P>
I totally agree that if this organ had a traditional feel to "playing " the Leslie with the speed switch,and hearing the rotors speed up and slow down,alot more people would have warmed up to it..the stationary 15" is great for pedal notes, but having a standard rotor under it would have given the cabinet more of the traditional Leslie "aural sensation". Hearing the transition from fast to slow or vice versa, is half of the whole allure to the Leslie effect, as far as I'm concerned. Sadly, they totally missed it on this one!</P>
Ah, thanks kkeys for the clarification. I have been disassembling a Rotosonic/Space generator Leslie 212s (Wurly) to make a passive cab, I understand now more. Mine had two Rotosonic drums, each had a traditional 2-speed motor stack, so it should be possible to replace the single-speed motor with a two-speed, and have it's fast/slow wired in with the horns'?</p>
I think some of these also switched the audio away from different speakers, that might be a bigger problem.</p>
thx-Scott S.

I'm with Scott here. Changing the Roto to a 2-speed, and then fixing the leslie switching so that the lower drawbar frequencies stayed permanently on the Roto would give you that ramp-up down.</p>
I'm told (not 100% certain of the veracity, but the guy worked for Hammond/Leslie in the UK) that, at the time, the combination of fast change over on horns plus (very) long changeover on the Roto was not liked for Hammond sounds. Remember that it was only a few years with the retirement of Laurens Hammond that the Hammond company finally 'accepted' leslies in their organs.

An X77 with two 710's or 715's should sound awesome.

It's not what you play. It's not how you play. It's the fact that you're playing that counts.
